Hello and welcome to this guide on how to be a better Engineer! As stated in my other guides I am in no means a Pro. I will start with the weapons first then work my way over to strategies, play styles, and more. If there is something I missed please tell me and also make sure to check other peoples guide for even more info. Or if I made a grammar mistake please tell me. :3

NOTE: The "[---]" are to make sure the pictures go in order so it doesn't look weird.

Now lets start with the Bread ad Butter of playing Engineer! The Wrench! The Wrench is used to upgrade and repair buildings. If you hit your building while it is constructing it will build 2.5 times faster! It also removes Sappers placed by Spies in two hits. This weapon is good in close range (obviously) and crits often. This is one of the most used Wrenches and used by lots of Engineer Mains.

The Jag! This is most likely the second most used Wrench. Upon hitting a building in construction it buils it 30% faster! The Jag also has a swing speed of 15% faster! Making this wrench good for a fast build or deploy. However it has a 20% slower repair rate and does 25% less damage meaning this wrench isnt the best in close combat.

The bane of my existence, the Gunslinger! This weapon is good for playing Battle Engie. It replaces the Sentry with a building from Hell, the Mini-Sentry. The Mini-Sentry takes 2.5 seconds, starts with 50% health on construction and gains health during construction to 100%, costs only 100 metal, rotates 35% faster, and fires 50% faster. It can't be upgraded but after the Gun Mettle update it can be repaired. (I like the old Gunslinger better) This "Wrench" also gives the wearer +25 more HP. Meaning Engie now has 150 Health. It does no random crits but if you hit any enemy in three hits without letting go of the attack button you get a crit. So in the famous word of Heavy, "You are ded. Not big souprice!" Taunting with the Gunslinger will perform the Organ Grinder Taunt Kill.

The bane of most Spies' existence, the Southern Hospitality. This Wrench is simple. You hit someone they bleed for 5 seconds, so if you hit a Spy and they go invisible you can see them. However you get no random crits since you cause people to bleed out. But if you use this Wrench you have a 20% vulnerability to fire. So in short terms, hit Spies and stay away from Pyros.

(Why is this text floating like 1 inch away from the picture?) Now the least used Wrench, the Eureka Effect. This wrench is good for a Ninjaneer or Offensive Engineer. This Wrench is leasted used because its just not that good. It has a 50% slower build speed and you get 50% less metal from Dispensers and Ammo Crates. However if you press the Reload Key (defaults to "R") you can teleport to Spawn or a Teleport Exit you have built. When you choose to teleport to a place Engineer performs a two second taunt where he hoists the Wrench into the air and is struck by lightning. (Yep.) The Wrench is good for placing a secret Teleport Exit then waiting for people to pass it. You then teleport behind them and kill them. Best when used with the Widowmaker. (Shotgun)

The good old trusty Shotgun! The Shotgun fires 10 pellets at a time every 0.6 seconds and can deliver high damage at close range, but has a high damage falloff over distance. The Shotgun holds 6 shots in its clip and you carry 32 rounds. (plus the 6) The weapon is best for keeping enemies at a distance.

The Frontier Justice! This weapon is great for TAKING REVENGE! This weapon gives you two guaranteed crits for every kill your Sentry gets, or one crit for every assist kill your Sentry gets. the Frontier Justice can hold up to 35 crits maximum. (You get the crits once the Sentry is destroyed.) But the gun only has 3 shots in its clip rather than 6. The Frontier Justice performs the Discord Taunt Kill. Can sometimes be paired up with a Gunslinger and be pretty good.

Another bane of my existence from Engineers who can aim! The Widowmaker! The Widowmaker takes Metal as Ammo but for every hit you get you get Metal back. (Depends on how much damage you do) This gun never has to reload. This gun if used correctly can be used to gain your metal back when there is not to be found. But with this gun you need to make every shot count as each shot takes 30 metal.

On of my favorite Shotguns, the Rescue Ranger! This Shotgun is great for keeping your buildings alive or great at Camping ! This Shotgun fire a bolt instead of bullets. If fired at a damaged building it repairs +75 HP without taking metal! You can also save your building by Right Clicking the building you point at for the cost of 100 metal. However it won't repair both sides of a Teleporter and can't remove sappers. Also the Shotgun carries less Ammo. It has 4 bolts in its clip and carries 16 extra bolts. So make your shots count!

The Pomson is know for being the anti-fun gun as it just ruins things for Medics and Spies. The gun fires an unreflectable team colored beam. If you hit a Medic they will lose 10% of their Ubercharge. (10% is the maximum and will do less after the beam travels 512 Hammer Units) If you hit a Spy they will lose 20% of their cloak; however they can still use the Dead Ringer. (20% is the maximum and will do less after the beam travels 512 Hammer Units) The gun can also light Huntsman arrows and only does 20% damage to buildings. It has an unlimited amount of beams but still has to reload 4 shots.

The Panic Attack. The gun has a 50% faster reload speed and deploys 50% faster. However it holds 0 bullets (Yes 0) unless you hold down the fire button where it then loads up a maximum of 4 rounds and releases them one-by-one very fast. However, with some updates you can now hold down continually to keep the shots loaded. But the less health you have the bigger the spread of bullets is making it a challenge at times to hit people. It is best used if you know someone is around a corner so you can load the shots and jump out. At close range all four shots will kill most players.

Secondaries are very useful and its a shame most Engineers forget they even have a secondary! The pistol is a great weapon especially when out of shotgun bullets. You should used the Pistol when you run out of Shotgun bullets / clips. Or if in close range and using the Rescue Ranger, Pomson, or Panic Attack. The Pistol has saved my life on more than one occasion. I was once took out four enemies one after another because I had the Rescue Ranger and was low on Ammo. (Plus I panic with it and miss) The Pistol carries 12 bullets in the clip and 200 extra bullets. (Dang Engie is prepared!)

The all mighty Wrangler! The Wrangler is a great choice for a secondary if you don't want to use the Pistol. (Why?) The Wrangler allows you to take control of your Sentry and aim and fire wherever you want! Or if you are "kewl" you can Sentry Jump. (Look it up if you want.) You can use the Wrangler to attack enemies out of Sentry range. Teach those Snipers who is the Boss!

The least used Secondary, the Short Circuit! (but very good Secondary) With this Secondary you can destroy projectiles. However its more difficult than the old Short Circuit, after the Gun Mettle Update it nerfed it even though most people didn't use it. Now you have to aim and Right Click to remove the projectile. Use this Secondary to protect your Buildings if you don't have a Pyro. (Or the Pyro can't airblast) The Short Circuit takes Metal as Ammo. Every attack takes 5 metal; however right click will take 15 Metal. (You have to right click to destroy it) It also has no Random Crits. (Thanks to SN for the following) After Gun Mettle Update the new Short Circuit can track cloaked spies now and tracks erratic scout movement. It now is useful for killing evasive classes as well as the primary projectile function.

The Level 1 Sentry takes 130 metal to build and each bullet does sixteen damage each. Without the Wrangler it will shoot an average of four bullets a second, but with the Wrangler it shoots an average of eight bullets a second. Without the Wrangler the Level 1 Sentry has a shielding 150 damage, but with the Wrangler the Sentry has a shielding of 450!

The Level 2 Sentry can protect itself for a bit longer but Level 3s are in most cases the best. As with all the Sentrys its bullets do sixteen damage each. It shoots an average of eight bullets per second without the Wrangler and an average of sixteen bullets a second with the Wrangler. Its base shield is 180 without the Wrangler and has a shielding of 540.

Now we have all mighty Sentry! The Level 3 Sentry! This Sentry (Like always) has bullets that do sixteen damage each. Just like the Level 2 Sentry it shoots an average of eight bullets per second without the Wrangler and an average of sixteen bullets a second with the Wrangler. However the Level 3 Sentry has something the other Sentrys don't have....a pulse! No just kidding it has Rockets! The Rockets do 50-150 but the falloff is calculated from the distance of the Engineer to the target, not from the Sentry to the target. So if possible stand closer to the target. (Without dying or course)

Now we have the dreaded Sentry from Hell. The Mini-Sentry! Its bullets do eight damage each and shoots an average of six bullets per second without the Wrangler and twelve bullets per second with the Wrangler. It has a shield of 100 without the Wrangler and 300 with the Wrangler.

"Did I throw a wrench into your plans?" The Spy will ruin your life if you don't prepare. He will Backstab you or Sap your Buildings when you are not looking. (Or maybe you are looking) So never keep your back in the open when Building / Repairing. You should swing once or twice then look behind you. Or put your back to a wall so they cant get behind you. Just make sure they don't get on top of you. Or they can (and will) backstab you. If a Spy just cloaked near you check on top of your Buildings, mainly Dispensers. The Dispenser will charge their cloak (only the invis-watch) so they can stay invisible forever. (Until they move) If you learn to listen you will notice that decloak sounds are loudish. (Following is from Draco_314 ) "Spies will often wait until a more opportune time to decloak than just out of the blue, usually when the engie has bigger problems (e.g. a push) or a building is placed/upgraded to mask the sound of the decloak and hide their approach. Now that the Wrench can hit the buildings under you when you're standing on top of them, I recommend doing that under a ledge so a Spy has no possible way of jumping on top of you and getting the stab."

"Here's a gadget you should build: one what stops my bullets!" A good Sniper (or a bad one) can take you out easy and without having to face your Sentry. Good rule for every class is to never stand still. If you stand still you are an easy target to any attack. The problem with your Sentry is that it can't move unless you move it. So if a Sniper spots your Sentry all they have to do is charge their shot and take it out easy. If a Sniper is targeting your Sentry your best chance is to use the Wrangler if you have it or get one of your teammates to take them down. If you have a Pybro (Yes Pybro) and they have a flare gun (scorch shot, etc.) have them try to light the Sniper on fire, they will most likely move and at the least miss their shot.

"Go on and build more o' yer little guns. I'll shove every one of them up yer arse!" Any good Demoman will be a bother to your Buildings. (and you) Just like the Sniper they can attack from a distance. (but they are closer) They also have the advantage that their weapon arches, meaning they can attack from right under even easier. Your best chance to have the Short Circuit so you can remove their Stickys / Pills. If you are using the Wrangler take them out asap!

Now lets get to the fun part of this guide, the Play Styles!

Engineer is one of the best classes to be if you are defending. This play style you pretty much just stay at your "base" that you make and make sure the other team doesn't break your defense.

Not to be confused with the Battle Engineer. This play style you don't really see that often as it is harder to do. In this Play Style you need to move your Sentry close to the Front Lines but make sure you don't put it to close that it gets destroyed in two seconds. Your job is to make sure your team doesn't lose any ground and to make sure the enemies don't get to close.

My second favorite Play Style, the Battle Engie. The Battle Engie carries the Eureka Effect or Gunslinger. (I use Gunslinger) If using the Eureka Effect place a secret teleporter
exit and wait for the other team to move forward a few checkpoints (or Control Points or whatever it is) and then teleport from behind and kill them all! (Widowmaker recommended) The Battle Engie I play as uses the Gunslinger. You place your Mini-Sentry and when people get distracted / attacked by it finish them off when a few shotgun bullets to the face.

This is my favorite Engineer Play Style. Get behind the enemy (or go to their Spawn) and place a teleporter exit. Just use the Kill command to get back to Spawn. Place the Entrance and get your team in the teleporter. (Not to much to where you don't push the cart) Build your Sentry and Dispenser and kill the other team.

This is a fun style but is one that will make the other team mad. Place a Sentry in front of the door and have a buddy be a Spy on the other team. (They should use the Cloak and Dagger) Then they stay invisible right beside the door and their team dies and can't move!

Some random tips.

• If someone is running towards your building, hit them with your Shotgun from a distance. (aka Make sure its not a Spy)
  
  
• Sometimes you have to sacrifice a building to kill a Spy.
  
  
• Its sometimes better to kill the Spy and let your buildings be destroyed so you can rebuild and get stronger without that Spy around. (Goes with the Tip above)
  
  
• (Thanks again to SN for the following again)
  
  
• "The biggest sin of any Engineer is no matter what happens. If your buildings are destroyed, don't try to be rambo. Your life is far more important than a nest. If you die, your buildings will suffer the same fate as you and you won't be able to rebuild in time. If you live, you can rebuild quickly with what metal you have and stall for time. If all else fails, take cover and let your teammates do the work. Engineer is a weak class and no matter how well you can aim you will die from artillary classes and the like." - SN
  
  
• "Sentries halt pushes. Dispensers save lives, and Teleporters win games."
  
  
• "The biggest mistake of any Engineer is overextending. Most Engineers think aggressively rather than passively and attempt to spawncamp or even try to hold a heavily guarded enemy area by themselves."
  
  
• +IceBear | Hales Own Coin :3 : "i feel the need to say that if your aim is good enough you can take on power classes! WHOOOOOOOOOOSSS WITH MEHHHHHHHH!....... but seriously you can."
  
  
• (Goes with above) "Yes you can, but only if you can land meatshots consecutively or the enemy is weak. An experienced Soldier or Demo can whipe the floor with you in just two explosions at close range. Engineer has little to no ability to damage artillary classes with his pistol and his shotgun is for close range. Artillary classes have the added advantage of more damage from any range and soldiers are near impossible to take out with a shotgun as they can deck you with two splash shots. Which if one hits, it's usually going to juggle you and send you to inevitable doom, even if you have the edge. Never get close to one no matter how good your aim is. It's suicide usually and you'd be costing your own buildings as well as you won't be able to repair them since you're dead. It's foolish and should only be attempted if your nest is being protected by another Engineer. (Which is highly unlikely) If the enemy is being pocketed and you're directly in their sight, do not engage. Do what you can and protect your nest until either the uber push fails or you need to retreat. No matter how many meatshots you can land. Your aim will fail if you're juggled and meatshots do about 80-90 dmg per shot. A medigun heals around 20-30 hp per second and by the time you manage to do serious dmg it will have been healed. However, in the event you are out of the sight of the pair and they are not near your buildings, attempting to kill the Medic or simply weaken him is feasible and a good strategy if your buildings are safe. However, under most circumstances an Engineer should never engage stronger classes like that head on." - SN
