The co-op teams aren't your average player made teams. They try to stick together no matter what. Some of them even have special properties that players don't get access to. All of the co-op teams are comprimised of enemy bots, so they are limited in terms of how smart they are, but that doesn't mean they are all easy, as the special properties and overall toughness of their team and your own teams teamwork could easily change the tide of battle.

The easiest of the bunch. With a decent team you should have no problem with most of these.

MOB TEAM
Considered the easiest team in the game, these guys don't have any decent gear whatsoever. They walk around with sticks and only have beginner armour. But don't let that fool you because in groups they can be quite deadly, as they will endlessly spam dash attacks causing you to stagger everytime they hit you, leaving you open for more attacks which will ultimately lead to your doom. As for special properties, they have a massive amount of Anti-Material, meaning that they will do crazy damage to Ballistas, Cannons, Walls and even your gate if they get to a high enough level. Make sure to keep them back.

However, on their own, or in groups of 2 or 3, they are pathetic. Going down in a few hits to the back and not many to the front. if you use your skills correctly, they will be little to no problem at all.

KILLER TOMATOES?!?!
Yup. Food that wants you dead. Slightly harder than the Mob Team, this team comes with a range of classes, so they will most likely have support from Clerics and Mages. The Clerics in this team LOVE to start Happy Miracles, so if you see them group up, or you hear a teamskill about to go off, either interrupt them or run away as fast as you can. The Warriors are pretty weak, but they also deal a decent amount of damage, and one of them starts off with a rush from the start of the game, so be wary of going over bridges to fight these guys. Clerics, of course, are no good at fighting, but they almost always put Sacred Armour on all of their teammates, and when they are being hurt they will constantly heal them, so target Clerics before any of the other classes. The Mages aren't much of a threat as they usually don't put enchants on, but when they do, they can be the cause of your demise. They are mostly just an annoyance, firing from afar and occasionally stopping your attacks.

To beat them, just rush them and don't give them time to breath. Make sure to watch out for teamskills and rushes from the Warriors.

BAND OF MAGES
An entire team of Mages. This is where your shield becomes your best friend (unless you are a mage) Being a Mage against this team isn't reccommended as they use all the different enchants, so while you are being hit by fire (stopping your attacks), you will be slowed down by lightning, frozen by ice, and pushed back by wind, all at the same time. As for the mages themselves, they are squishy. Again, being taken down in a few hits, and no shields to guard themselves, they often run away after being hurt. It's generally best to walk up to them with your shield up, and guard attack or uppercut them when you are in front of them. Becareful about fireballs, as sometimes they can clip your character through your shield and turn you around, exposing you to more attacks. Make you are walking directly towards the mages with fire.

To beat them, use your shield often, have Clerics back you up with Sacred Armour and Heals (and resurrect if you die). And slowly push through their lines. Clerics with Dispel are very useful for taking out their enchants, it's always wise to have a dispel cleric behind you while you push up (Thanks Okami Chibiterasu!)

BAND OF WARRIORS
An entire team of Warriors, perfect for people with Warrior Slayer on their weapons. They have a decent defense and a decent attack power and they work together quite well. Again, watch out for dash attacks as they can drop you quite quickly since they are more powerful team, especially if they are hitting you in the back. Unlike the Mob Team, they don't have crazy Anti-Material, so you don't have to worry too much about dying while on a cannon or ballista, unless they group up on you. Becareful about using your shield against this team as they will try to get behind you and cause massive damage, or they will group up and uppercut you to leave you open to others that attack. It's recommended to get behind them as much as possible, as you can deal the most damage then. This team usually starts Cheers at the start of the match, giving them a headstart on levels and a HP boost, making them harder to take down for the first time.

To beat them, either out range them as Mages, or rush them with all of the classes in a big group. Use teamskills and storm their castle, have warriors guard Clerics taking down the tower and mages supporting from the stairs with lightning strikes.

BAND OF CLERICS
An entire team of Clerics. These guys are a pain. They would be easy to kill, but since they are all Clerics, they will always be constantly getting healed and protected with Sacred Armour by the Clerics in the vicinity. These are more dangerous than most other round 1 teams, as half of them carry KO effect hammers around, which KO you 9/10 times they hit you, effectively locking you in place until you die. The ones with said hammers are the Clerics carrying Blue and Grey hammers. Shields are helpful against this team, but don't rely on guard attack much, as you won't be dealing enough damage to stop your target from being healed. As individuals, they are weak, Low defence, Low attack. The only thing you have to look out for is the KO Effect hammers, as they can kill you very quickly, especially from behind.

To beat them, gather the Clerics in groups and kill them all at once as a team. Mages are almost essential against this team, as they build ballistas like crazy and have massive tactical power-up, so you will take tons of damage from, Ballistas, cannons and bomb rocks.

HEAVY DUDES
An entire team of fat! These guys have a mix of classes, but the ones you should be worried about are the warriors. Again, keep them away from Clerics, but the Warriors will spam rush to no end. The only chance you have at getting damage in is after a rush is finished. The warriors themselves are basically walking tanks. They are slow, but can take tons of damage, however, they don't do much damage when they are not rushing you, as their weapons are weak. Clerics are the most annoying of the bunch, being able to heal and put Sacred Armour on to protect themselves, while having the same, if not more, health than the warriors. They are slow and their weapons are weak. The Mages are pathetic. They have little health, but are slightly faster than the other classes. They don't put enchants on very often and there isn't many of them (usually around 2 or 3). Just make sure to stay in the open in case you get hit by rushes. If you get hit into a corner, it's over for you.

To beat them, Lead them near edges and smash them off for a quick kill. This isn't needed for the mages, as they literally run around with a target on their face.

ROBO-BRIGADE
Taking Rocketman spam to a whole new level. This teams Warriors ADORE using Rocketman. It's what makes them so annoying, that and the fact that they have smash power up 4/5, so trying to fight them on bridges and near edges is basically suicide. Them and their Clerics are pretty weak, but don't underestimate them, as the Clerics have Stun Effect, which is more powerful than KO, as it lasts longer. The Mages can be frustrating when they stick near the other classes, as they favour lightning which in itself, is broken. There is one enemy you have to look out for, a Red Mage known as IQ9. He is pretty tanky when it comes to health, and once again, favours lightning. However, if you keep hitting him in the back he should go down easily.

To beat them, work as a team. You are going to need Clerics against these guys, have Support Clerics stay back and keep teammates alive, while dispel clerics make sure that the enemy mages don't keep using their lightning on teammates.

NINJA CLAN (MAJOR ENEMY!)
(Continued in next section)

NINJA CLAN (MAJOR ENEMY!)
The fastest of all the teams. Another all warrior team and the only major enemy in round 1, these guys are nothing to be taken lightly. Their warriors are stronger than the average warrior but they go down quickly if you hit them in the back often. They love to use spinning blade and often use it in their combos, so a shield helps greatly when you are trapped and they start spinning. Trying to run away from them is just silly, as they will group up on you and dash attack you to death. If you want to get away from them, run circles or back away with your shield up until teammates come to support, as the way the AI works means that they will not stop chasing you until you either run far enough away, you die, or they die. There is only one of them you should fear more than the others, and that's HANZO. He is basically the tank of the group, being able to take much more damage than the others and having a slightly stronger smash power-up.

To beat them, move through them slow and make sure to try and separate them if you are a mage, get Clerics to spam heal and attack from behind while you draw their attention from the front. They move fast and respawn fast, so you will need protection while you destroy the tower (Although if you get in their castle you can just keep killing them without destroying the tower for more points)

That's the end of the Round 1 enemies. It only gets harder from here...

This Tier contains some of the harder and more annoying teams, so be ready for a fight, there's plenty of Major Enemies for you to face.

FIRE ELEMENTALS
A team about using nothing but fire. This team consists of Warriors and Mages, but they all have 1 thing in common, they all use the fire enchant. This means that they will be doing extra damage and stopping you from attacking them head on. Circle around the mages to avoid their fireballs, then use a shield to inch towards them and attack. The warriors are more difficult, even though they don't take much damage, they have powerful weapons, with KO Effect, Fire Enchant and a lot of damage. If they manage to get behind you, you could die immediately, as they would deal damage with their weapons, smash you away and then quickly dash attack over to you. To avoid this, use your shields to walk backwards while attacking them (if you are a warrior) For Clerics, walk backwards with your shield until you are a good distance away then circle around them and proceed to eitehr turn back to fight (High Risk, high reward) or find teammates to help you. Zig-zag to make sure you don't get hit with rocks from behind.

To beat this team, Warriors and Clerics. You will need lots. Remember, even though their entire team consists of fire enchantments, they are not immune to them.

WIND ELEMENTALS
This team...will be a massive pain to every fiber of your body. The same setup as the fire elementals, except now, their mages and warriors have more health and all use the wind enchant...JOY! Of course, every time they hit you they will push you around and deal lots of damage at the same time. They have seemingly infinite AP as they can trap you in a corner pretty much forever. As a group, they are almost unstoppable, when split up, they become much weaker, but still pose a threat, especially the warriors, as they have KO effect and wind. The mages love to set wind traps all over the place, so group rushes, or normal rushes, are not a wise idea. Shields are almost a must against this team, it will let you get out of tight situations without being pushed around constantly until death. Clerics are also a must, as destroying the big tower is going to be the hardest part of the game, so you will need Clerics to heal and revive while others tower tap away.

To beat this team, Warriors and Clerics are your main focus when it comes to player made teams. Mages will get pummled to death the moment they get involved in a fight.

BLACKSMITH HELPERS
A full cleric team. These guys are essenstially a more powerful Band of Clerics, not having as many KO Clerics, but instead having Stun Clerics and Lightning enchanted Clerics who are sure to ruin your day. There is one Cleric you should be wary of, JINGORO. He is extremely tanky and has a KO Hammer, that can kill you quickly from behind. These Clerics don't heal and support each other as much as the Band of Clerics do, but will backdoor you if you don't check on them. Mages are extremely useful against this team, just like they are against any team with a lot of Clerics, as it will keep Ballistas from shooting at your teammates too often.

To beat this team, Rush them with Mages and Clerics, then have the warriors spawn kill them while Clerics beat the tower down.

FIREFIGHTERS
A team of mostly Clerics, with a Mage and warriors on the side. Being another fire oriented team, they do a lot of damage, however, they lack good armour to keep them alive. What keeps them alive is each other, being clerics they will constantly heal each other. This is also the return of KO Clerics. Clerics with Golden Hammers will KO you with each hit, they also seem to be more aggressive than the other Cleric teams. The mage is weak, but annoying. Since they sit from afar and constantly fire at you with fireballs, it can be quite hard to kill them in a head on attack. Circle around them and use your shield (or wind if you are mage) to more forward and attack.

To beat this team, look out for backdoorers, and make sure that friendly mages take out the ballistas on the enemy castle.

SUPER ROBOTS (MAJOR ENEMY!)
You thought the rocket spam was over? NOPE. A much more powerful version of the Robo-brigade team, these guys don't let up, and use all the classes. So once again, target Clerics first, especially one known as Dr. Airhead, one of the 3 tanks in the team. The other 2 being mages, they all take tons of damage, and can be healed at any time either by themselves (only Dr. Airhead), or other clerics. The Warriors are pretty tough. Some of them spam rocket man, while others move in for the kill with powerful swords with stun and lightning on them. You don't want them to get behind you otherwise consider yourself screwed, as they do massive damage from behind. As for the mages, they are just really tanky and they love to use lightning.

To beat them, good teamwork is a must. You need a balance of every class in your team, Warriors on the front line, Clerics healing them and Mages staying behind the Clerics firing from afar with fireballs, lightning and ice.

DEMONIC KNIGHTS (MAJOR ENEMY!)
Oh boy...What's not to say about this team? They are all warriors, they deal massive damage and they can take tons of damage. They have the special anti-material property, so they can take constructions down very fast. At level 4 and above, they can take your gate down in seconds if they group up to attack your castle. Best thing to do is to constantly lead them around and make sure they don't hit your gate too much if all else fails.

To beat this team, equip a warrior with smash power up 1, 2 and 3, and uppercut 1, 2 and 3 (2 and 3 is optional but it is easier to kill them with uppercut if you do have those buffs) Lead them near edges and constantly smash them off of the edge. If timed right, you can hit multiple enemies at once with one smash or uppercut, protect Clerics when they advance up, and help mages deal with lone enemies, as the demonic knights have massive physical defence, but barely any magical defence, making taking them down with mage a lot easier.

SAND PEOPLE
A team mostly of warriors, but has some mages and clerics. You've seen rocketman spam, now we get into the nitty gritty no skill rush spam. The warriors are very weak, having around the same health as the mob team, the only special property that some of them have is anti-material (also this is really only noticed on the mages) They do a lot of damage from behind and love to spam rush a lot. They do way more damage than the Heavy Dudes, making them a bigger threat. The clerics are pretty easy, once you take off their sacred armour, they are pretty much done for. The mages are also easy, except for one, who has the same name as a warrior. He can tank tons of hits, but his weapon is weak, apart from the massive anti-material.

To beat this team, avoid rushes and make sure not to miss them running past you. Kill them and move up and becareful when on a cannon, as the mages will go after you and most likely kill you unexpectedly due to anti-material.

SPACE ALIENS
These guys were in the campaign too. The warriors love rocketman, not quite as much as the robots, but still enough to cause a problem. The mages love to be annoying, and it's not a good idea to be a mage since the warriors will pummel you. The Clerics are easy to kill but they spam heal so much and can often act as a distraction for you, to go and kill them so the enemies can surprise you. There is one tank on this team, known as CREATURE. He has tons of health, his weapon does a decent amount of damage and most of all...Smash power up 5/6. If he hits you, you will go flying, so becareful when near the edge of the map.

To beat this team, avoid rocketmans, work as a group to target the Clerics and advance up. Mages should destroy ballistas.

Tier 3 teams are the hardest of the bunch, having the most major enemies and generally being tough. They are definately something to fear and you may even recognize some of them from the campaign. There is also one secret team that are extremely rare, but are VERY hard to defeat. Think of them as the doom bots from League of Legends.

ICE ELEMENTALS
Brrrr! It's cold here...Just like any other elemental team, they are a team mostly comprimising of Mages, with a few warriors on hand (who don't have shields for some reason). There is one tanky mage who you should look out for, called Ice Demon. The mages have more health than the average mage, say from another elemental team. The Warriors have a decent amount of health too, but do little damage, their KO Effect makes up for this. They are quite slow too and lack shields, but they can still guard themselves from damage somehow. As their name suggests they will all be using the Ice Enchant.

To beat this team, outrange them with longer attacks. You will NEED Ice Resistance to survive this team, Ice resistance 2/3 will be enough to stop them from freezing you every second, especially when you get in their castle. Clerics are a must for this team.

SPOOKS
2spooky4u. I wonder why they aren't called the Lightning Elementals. This team is mostly Mage and Warrior, but they have 1 Cleric, who is extremely tanky, known as GHOST KING. Apart from Ghost King, the members of this team mostly have low health, but they all use lightning enchant, so moving through them is usually a pain, especially when you have to get to the Ghost King to kill him and stop him healing the rest of them. Ghost King himself is very annoying for a Cleric. Wielding a KO hammer, he can take tons of damage before dying and at the start of the game he will always be seen back at his castle building, rarely leaving to support and battle.

To beat this team, focus on the mages before the Warriors. Shields will be needed against both Warriors and Mages, especially to avoid their lightning enchants. If you get the chance, smash Ghost king of the edge for a quick kill.

LIVING DEAD
One man....Decided that he wanted to make zombies for some reason, then became one himself...That man, is Doctor Airhead. He really is a Airhead. Ahem. Anyway, these guys are fast and mean. They may have low health, but they do a ton of damage to make up for it. The spartan zombies and the blue zombies should be your major concern, Spartan Zombies constantly rush and they can kill you in one hit from behind sometimes, while the blue zombies are fast and have powerful weapons with a special property, Stun Effect. I know stun effect is a buff that you can normally get, but the special property of these guys means they will stun you 9/10 times they hit you, making gettting hit once fatal. Titus (a cleric) also has this property. There are two tanky units in this team, Dr Airhead and my rival E-Z ZombieMaker. This guys smash is so ridiculous that it even goes further than my Smash power up 6 Warriors, and he loves to use it a ton. Rivals since Xbox.

To beat this team, grab some high damage Warriors and spinning blade them. Their low health will make it easy for you to wipe out groups of them. Just watch out of the blue zombies and spartan zombies.

SAMURAI CLAN
Essentially a harder version of the Ninja Clan from round 1, these guys have large amounts of health and do large amounts of damage, but are slower than the average warrior. There are two Ninja's on thier team that run way faster, but have less health and do less damage. Whatever you do, do not let them get behind you. They can deal massive damage from behind. This team is a full warrior team.

To beat this team, Warrior slayers are helpful against these guys, but Smash Warriors are just as effective. Be sure to equip a fire enchant and constantly hit them in the back.

TEAM CASINO
They got angry at you for getting so lucky on the happy spinner, so they've come to finish you. This is a full team of Mages. Some are tanky, some are squishy. They each use different enchants and love to spam very damaging Wind Traps. Handler seems to dislike using magic, so instead he will constantly run at you trying to melee you. He has low magic attack and a high physical attack meaning he will do a lot of damage. Depending on how many players there are in the game, you will have a chance of being able to vs Ms.TY from the Happy Spinner (there are two Ms.TY's).

To beat this team, it's not recommended to play as a Mage unless you can out range the enemy with Fireballs and Ice. Shields are very important against this team, and so are Clerics.

GRAPPLERS
For a name like that, they sure don't do much grabbing. This team only has one mage who is very tanky. He can do a ton of damage so focus on getting him out of the picture first, then focus on the Clerics. Becareful of their KO weapons and be wary of the amount of health they have. While not being massively tanky, they have more health than the Warriors. The Warriors, while having no armour, have powerful weapons that can potentially 1 hit kill you. Some of them spam rush while the others spam dash attacks.

To beat this team, High damage classes are great against this team. Having a smash warrior or two can help against the mage and Clerics. Don't let the warriors get to your back.

LIGHT TEAM (MAJOR ENEMY!)
Look! It's your buddies from the campaign! Or so they were. This team is a mix of classes and all of the units, but one (KING), within this team are extremely tanky and can do a good amount of damage, unlike their pathetic campaign counter-parts. In addition, there are some characters you didn't see in the campaign, along side the ones you did. Jack loves to spam rushes and can do a lot of damage if he hits you from behind, so watch out for him. Lian is very slow, but very tanky.

To beat this team, Smash warriors are recommended. Group them up then smash them all off at once to allow teammates to push up and take towers. Prevent KING from staying alive too long, him and Bob love to start miracles.

DARK TEAM (MAJOR ENEMY!)
Like the Light Team, but harder. This team contains mostly the same set-up as the Light Team, but have many more damaging and tanky units. UNDEAD should be one of your main prorities, he has the most health of the entire team and is a Cleric. Marshall loves to spam wind traps and has a massively decreased cooldown timer on his skils, allowing him to use them more often. This team has a few references to the campaign too. The enemy names "Princess?" is reference to the very last mission, while BUKET HEAD is the gatekeeper enemy in the first mission and Strong Bucket from the first level in the last missions.

To beat this team, you will need a very strong and well co-ordinated team to take these guys on. You will need Clerics with Resurrect, Sacred Armour and Sacred Songs. Warriors will need to be at their strongest, smash 6 is preferred. Mages need to keep hitting them with Ice and Fire to keep them in place.

And lastly...The team that everyone fears.

THE SUPER VILE BUNCH (And you guessed it, MAJOR ENEMY!) (phenomenally rare)
Have mercy...These little yellow men of doom should be your worst fear in co-op. With a mix of classes, they are ALL tanky with absolute HUGE amounts of health. The Warriors can wipe out over half of your health with one hit and they all have Smash Power up 6, the Mages sit from afar and deal tons of damage with their fireballs and the Clerics are just generally annoying, constantly healing everyone. If they all gang up on you at once, consider yourself returning to the respawn screen. Even the pro players of the Xbox edition lose against this team sometimes (when they aren't backdooring). Do not even try to go one on one with these guys unless you are planning to smash them off the map.

To beat this team, use everything you have learned. One mistake could cost you the game.

A lot of things have changed on the Xbox version of the game, and I think I'm ready to add the Co-op teams for Xbox into this guide. Some teams were either removed or changed slightly for the new co-op. There's also rewards that you can get for playing and earning co-op points. Multiple bosses were also added, but I will list the changes in a different section.
This section will list all the co-op teams for the normal difficulty of co-op (there's 2 modes now, Normal and Hells Challenge).

So let's get started!

Returning Mob Team

Once the easiest team in the game, now an extremely frustrating trainwreck of a team. The Returning Mob Team, as the name suggests, is the Mob Team, but now way more powerful compared to their old counterparts. This team now comes with boosted stats, evolved weapons and actual armor. However, what makes this team so frustrating is the fact that every one of them uses Rush and Shield Charge, which in groups could lead to a very swift death if you even get hit once.
Their defense is slightly higher since now some of them have armor, but they are still relatively easy to kill. Their attack has skyrocketed however, some of them use evolved weapons, others use super premium weapons, still all deadly.
Super guard warriors and mages are going to be your friend here. They have lower magic defense than normal, just don't get too close. Any long range attacks should be useful against this team. Fireballs, wind traps and napalm recommended.

100 Year Sentence

A full team of Berserkers. This team is easy to kill, but if they get behind you, you're finished. The gimmick of this team is their insane ambush stats. 1 hit from behind can kill you, so don't turn your back on them. They move relatively quickly too, but they don't seem to use Double Spinning Blade very much, if at all. This team also has a ton of uppercut/smash power up, so make sure to try and stay away from edges if you can.
Mages and Fast Guard Attack warriors are great against this team. If you have Fast Guard Attack and Super Guard, just be sure to back up into a corner, otherwise you'll die if one of the bots get behind you.

Crazy Tornado+

Another team of Berserkers (with a few zephyrs if you have enough players). This team is very different in the fact that they will rarely build towers and instead rush straight for your castle, even at the start. This team will CONSTANTLY use Double Spinning Blade, so playing as a Berserker is not recommended at all. They're also slightly faster while spinning than usual. Mages with Warrior slayer or Warrior with Stun/KO and Fast Guard Attack will wreck this team.
Treat this team like you'd treat new players using Berserkers.

Honey Hungry Bears

One of my personal favorites. An adorable team of Clerics all dressed in bear suits. This team isn't particularly strong, but they love to spam Happy Miracles, sometimes up to 6 in a row! Most of the time they will do this when their castle is breached but every now and again they will miracle when they're near players.
Any class is good against this team due to their low attack and defense stats.

War Dogs

War never changes. A team mixed with Mages, Berserkers and Warriors. There's nothing really special about this team, mostly average apart from their slightly increased damage. The Mages don't really shoot magic too often, they'll often rely on Melee and Lightning Strikes. The lack of Clerics means that if you take the beginning ballistas down, you won't have to fear about being shot at.

Forest Friends

A team with a mix of Mages and Clerics. This team actually features a couple of Honey Hungry Bears too, but in this team they will try to rush your castle from the start while the other bots take towers and fight. Nothing really special about this team, but they are all wearing animal outfits. The mages can be a bit of a pain if they have ice or fire enchants but nothing team wipe worthy.
Dispel Clerics are useful for going against mages and lightning mages are nice for the initial cleric rush.

Pizza in Delivery

I despise this team too. This team consists of mainly Warriors, but having enough players will result in Clerics spawning too. This teams damage is slightly higher than average, and one of the warriors always starts with Rush (a very powerful and annoying rush). While they have the Executioners Blade, they don't seem to use Stun Effect on it. The Clerics love to spam Dispel and Sanctuary, so having a dispel Cleric with you is effective if the enemy Clerics are around. It's wise to target them first. Support Clerics along with usual classes are great against this team, especially if said Support Clerics have Fast Resurrect.

Lady's Garden

Couldn't have chosen a better name? This team consists of Clerics and Warriors. They are relatively strong, some of them using evolved weapons. The real focus is on the bot called Marie (Marie used to be the community manager for Toylogic until she mysteriously disappeared...) Having Extra attack range, Stun, Stun Crusher and more aggressive than the other bots in the team. They don't have a lot of defense though, so if you have a strong weapon you should be good as long as the clerics aren't around to heal everyone back up.

Agents

A team consisting of Mages, Warriors and Clerics. This team is mostly mages. Nothing super special about them, but the Warrior that spawns likes to spam a rush that is pretty difficult to avoid and also has increased smash power. Try to watch out for Windtraps since this is a mainly mage team. Warriors are recommended due to shield and guard attack.

Big Family

Why does this team have to exist? This team consists of Warriors, Clerics and a single Mage. The Warriors are super fast and spam roar to no end (PAPA does tons of damage and has an OP rocketman), the Clerics will spam heal on just about everything and the only Mage has smash effect on a Cyclone. This team sucks, just sayin'. Shields are your best friend here and you'll need quick reactions due to this teams high mobility.

Some old teams also make a return, but they are relatively the same.

And now for some of the hardest co-op teams of all time. Again a few old teams will appear (Super Vile bunch, Dark Team, Light Team). I will be listing the new teams. The Grim Reapers also get some boosts, mainly HP, attack and attack speed.

100,000 Year Sentence

Back stronger than ever. An ultra powered version of the 100 Year Sentence from normal co-op, these guys basically now have a ton of health, even more damage and an even bigger chance to 1 shot you from behind.

Martial Mastery

Unfairness incarnate. This team consists of incredibly strong warriors with insane anti-guard attack stats. Putting your shield up against this team is basically useless, as they can 2 shot you through your shield. On top of that they also do a ton of damage when hitting you normally. Super Guard is almost a requirement against this team. They have slightly less HP that other hells challenge teams, but that doesn't make them any less difficult.

Developers

Now you can say you beat the Developers. This team consists of Warriors, Mages and Clerics. The bots on this team all have names of the Developers (duh) and have a ton of health. They deal slightly more than average damage. But other than that they're actually not the most difficult team in Hells Challenge...

Angry Ladies

Lady's Garden after a long day of work. This team consists of the same bots seen in Lady's Garden, but now super powered. They have a ton of health and deal way more damage along with being even more aggressive. Even Marie is back.

Crazy Tornado Pro

Faster than ever. The upgraded version of Crazy Tornado+, these guys have a very fast movement speed when spinning and much more health, as well as slightly increased damage. Other than that, nothing new.

Ultimate Mob Team

And you thought the Returning Mob Team were annoying...The Ultimate Mob Team is an upgraded version of the Returning Mob Team. More damage, more HP, more annoyance.

Meteoron Nest

A full team of Mages that love meteors. This teams main gimmick is their Meteor storm spamming, especially when you're in the castle. They mainly use the Fire enchantment and can be pretty deadly in groups. High HP/Defense means that smashing them off the edge is the most efficient way to kill them. Playing as Mage isn't recommended.

Rampaging Locomotive

All aboard. This team consists of Engineers with high HP and Defense. They like to place Remote Bombs and use sanctuaries to heal themselves. They have a lot of Smash power up and their Remote Bombs do plenty of damage, so be sure to look out for them.

Rampaging Robo Team

Literally a team of iron men. This team is basically an upgraded version of the Robot teams from the past, except this time they have the MARK robots to help them. The MARK robots have a ton of health, do a ton of damage, have extra range on all of their attacks and will not flinch from taking damage. This means that the only way they can be stopped is by being killed or lead back to their castle. Apparently fire works well on them. This is one of the hardest teams in Hells Challenge due to the MARK robots.
Super Guard warriors are basically a requirement.

Since the overhaul, co-op on Xbox has gotten some new and old bosses so that it plays out more like a special challenge.

Grim Reaper

The Grim Reaper spawns most of the time after breaching the castle gate, but can spawn before too. There are 3 classes it can spawn has, each with different attacks and immunities. All Grim Reapers have Smash effect on their weapons. If the Grim Reaper does 3 normal attacks in a row, it's next 2 attacks will stun you and then send you flying VERY far away (if you're directly under the grim reaper when he slams the ground you will just get stunned again instead.)

Warrior: The Grim Reapers Warrior form is immune to Mages and Warriors, so Clerics are the only class that can damage it. It mainly uses Uppercuts and Smash to attack. It's smash range is massive and most of the time won't send you flying, but instead will just deal some damage.

Berserker: The Grim Reapers Berserker form is immune to Warriors and Clerics, so Mages are the only class that can damage it. It mainly uses normal attacks to combo into uppercuts. It will also constantly use Berserk which enables it to slowly regen health and of course increasing it's damage. Every now and again it will use Double Spinning Blade, if you get caught by it and you're close to the grim reaper, you will die. The Grim Reaper has almost infinite AP so Super Guard is required to survive a full spin (or a lot of recovery/max HP).

Mage: The Grim Reapers Mage form is immune to Mages and Clerics, so Warriors are the only class that can damage it. It mainly uses lightning strikes and normal attacks. Whenever it uses a lightning strike it will use a warriors roar at the start, after the lightning strike is set down it will launch out a wave of Magic Napalm which does massive damage and will probably kill you if you get hit by it. It also has Stun effect on it's weapon, as well as Smash effect.

Gatekeeper

This Mini-boss spawns when the gate has been damaged enough. He uses the fast versions of Roar and Smash, so his combos can be quick and deadly, considering his weapon has a lot of ambush (Great Mithral Axe). His roar also has a pretty big radius. He will constantly use Super Guard and Fast Guard attack to combo into other skills.

Builder

The builder spawns when your team has all the towers captured. His only objective is to build towers and he's very quick at it. His weapon has smash effect and smash power up, but he will only attack if you're infront of him. He is pretty fast so try to use a lightning mage to slow him down. If any towers he has recently built are destroyed he will turn around and come back to build it back up.

Gate Crasher

Gate Crasher spawns randomly sometime into the match after your team gets enough score. He will then make his way to your castle ignoring and pushing everything in his path out of the way. As soon as he touches your castle gate it will be destroyed. He will try to take the big tower if he can but very slowly. Kill him before he reaches your castle to save the gate.

Dr. Airhead

Dr. Airhead spawns randomly sometime into the match after your team gets enough score. His arrival increases the power of all the enemies you're facing. He is weak but very fast. Lightning mage is heavily recommended to take him down easily. Defeat him to make sure the enemies powers don't last.

NO FACE+ (Hells Challenge only)

NO FACE+ is an enemy that spawns sometime into the match. He is a Berserker much like the Berserker Grim reaper, except he isn't immune to any classes. He attacks like the Berserker Grim Reaper but uses Double Spinning Blade much more often and doesn't use Berserk. Unlike the Grim Reaper he will try to push towers if possible.

Team Leaders

Each team now has a specific boss called the Team Leader. They are boss like enemies that appear after a certain amount of kills has been reached. They use the charateristics of whichever team you're facing.

Bonus Monster

The Bonus Monster is a super fast but super weak enemy that spawns usually around the beginning of a match and offers a high XP reward to anyone who can kill her (yes it's Female). She rarely attacks, but if she does try to attack, run the other way. Her weapon is a 1 - 2 hit kill (somehow).
