Im still playing this ♥♥♥♥ so it is obviously incomplete and there might be more effective ways of doing some things, so please let me know in the comments if you found something cool and i will add it here for other people to see, this is a very confusing and deep game so im trying my best to document as much as i can.

I will try to list weapons from NPCs that respawn, if there is a gun tied to a Quest NPC i will give due warning.

Kinda obvious but spoiler warning ahead.

Enjoy.

UPDATE 03/28/2025: I wrote this quite hastily and I realize I made some mistakes in the details on how to get some of these guns/parts, if you spot something that is not right let me know and I will fix it. I also think we have listed most of the guns in the game right now, but there are some areas I haven't fully explored and secrets I'm sure have not been fully discovered so I will leave this still as a WIP.

Thanks to everyone who contributed, some of the guns and parts listed here i would have never found them by myself (I'm just a regular mortal with a 9 to 5 job), so while I'm the author of the guide there were some absolute W Based contributors that I want to thank directly by crediting them on this guide next to the weapons/parts they found. If you are mentioned in this guide you are simply awesome, thank you.

I recommend buying the heaviest mech (Stalker) parts (legs, armor, core) and leveling up your strength and speed to carry heavier equipment (If level cost gets too high start leveling up your LACK, as this decreases your level ergo the cost of leveling up without any repercussion to your stats, JUST BE WARNED IT ALSO INCREASES CHANCE OF ADDITIONAL ENEMY SPAWNS), also try to buy as many EFP stocks as possible to increase your daily income. i DONT recommend buying Stalker weapons and small arms since many you can get them exploring for free as i show you on this guide
[/olist]

Even with the best purchasable gear you're still squishy try playing tactically/being a rat.

I also recommend equipping your starting Stalker with the following weapons you receive (assuming you picked detective), 2 revolvers MR-37V for Stalker killing and one gatling gun FM SB900 for human enemies. That will pretty much be the trend through the game, heavy and precise hard-hitting weapons for stalkers, and cheap high-fire-rate guns for on-foot personnel

Always talk to people even to those you already have, you never know when they might have new dialogue options

Side quests are not broken (maybe just 1), sometimes you need to talk to an NPC to finish it or kill somebody.

Check the other guides if you're lost on what stats do or how to hack.

This game rewards exploration quite heavily, give it a try before checking out this guide, you also get rewarded with fun dialogue and tips on where to go to finish the quest by talking to NPCs, even those that seem unimportant.

You can finish the game quite quickly, the main quest is not dependent on side quests, you actually just need to interact with a single NPC and Lorenzo to finish the game, and travel quite far...

An incredible gun for starting out, Euros-12 is an automatic shotgun with decent mag size and good damage, only struggling against more armored opponents, you find this outside the ACTF cellblock, which is accessible through the lobby, there will be two guards that respawn so no risk in killing them, and the EFP personnel won't aggro you for killing them unless you accidentally hit somebody else, I recommend dual wielding the revolvers with "4" to kill them at point-blank as they are somewhat armored

Inside the cellblock the ACTF officers in a kiosk in the center of cells carry the HX AP5, a light submachine gun with multiple firing modes, they can also be killed without repercussions. Be careful as even if you didn't aggro any ACTF personnel as soon as they see you they will shoot with deathly accuracy

https://images.steamusercontent.com/ugc/40075427754063167/32397AB994EC99467DE012624349059429CD1F9F/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false

You can find the FM B90, one of the best secondary weapons, and the HX G6, a good rifle for armored targets outside your office to your right, the two NPCs are near the vending machine, they respawn so no risk in killing them for their guns.

Immediately to the left of your office, there is a small couch lounge with an NPC carrying the Five-septeM, a pistol

Inside the Evidence Room behind an armored door is the FM Five-septeM-S and FM B90S, the silenced version of their non "S" counterparts you find in the offices as well. I could not find the code to open the door, however, you can pick a Stalker weapon from the garage and break the door that way, nobody will attack you for it. A 25mm gun did the trick for me

Thanks to MACMAN2003 for finding the code to the evidence room door, it is 725

ONLY THE FIRST TIME YOU LEAVE HQ outside the garage there will be an NPC shooting at you near the street with the Mosin-Nagant, a WW2 era semiauto gun, pick it up or you'll lose it when reloading the area

Inside the apartment building SEE SCREENSHOT, you can find the Minato M9, a submachine gun, in the locked apartment across from Keith Morrow Apartment, BE WARNED THIS IS A QUEST NPC so he won't respawn and if you kick his door he will be immediately aggro. Keith Morrow with low hostility will give you a quest for the figurine in that apartment, so you might as well do it if you want the Minato M9

https://images.steamusercontent.com/ugc/40075427754116059/0EE816A7B63C0E2B2611282E2E72195B1367693C/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false

One floor above you can find your apartment, inside your bedroom you will find the dagger.

Across your apartment will be another one full of boxes, close to the windows above some boxes you will find the SSR 3001, a sniper rifle, JFK reference maybe?

MECH PARTS:
Sometimes when loading in a small stalker will spawn out of nowhere so be careful, you can kill it and it will drop the Cord-12.7mm, a decent Stalker killer and the V134 Smallgun, one of the best bullet-based antipersonnel Stalker weapons.

The EFP stalkers outside the HQ entrance also drop the Cord-12.7mm, be careful as they are very strong, especially in the early game but you can use the street wall as cover and snipe them somewhat easily.

There are no extraction points here as far as im aware, you reach here by exiting the EFP garage and heading left on the street.

All enemies here have no armor and carry the OBJEKT 022, a very good rifle with great projectile mass and mag size that can carry you through the early-mid game.

STALKER PARTS:
There are around 4 small Stalkers that carry common weapons such as V134 Smallgun and Cord-12.7mm

Around the middle of the map, in front of a tent camp SEE SCREENSHOT there will be a bigger Stalker guarding the Rheinstahl VS-A atop an incomplete building, a heavy armor with much-improved weight almost half of the EFP heavy armor without any stat loss. It is a direct upgrade and a must-have, just be careful as the Stalker is much stronger than the small ones.

The big Stalker also carries the V167 Rotary Cannon, one of the best Stalker killing weapons in the game, although you can get it easier on the next zone if the stalker proves to be much trouble

https://images.steamusercontent.com/ugc/40075427754297740/28C6B1F0FF7EF9F19A2DA57EBF56CF22841227A4/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false

Enemies in the container buildings between the two bridges carry the Benedetta M6, a semiauto modern shotgun

STALKER PARTRS:

There are 4 small stalkers in this zone, 2 on each bridge. They carry the Parasonic 20mm rifle, kill them to pick it up. Haven't tried it too much but given it uses the same ammo as the V167 Rotary Cannon it might be a good alternative, sacrificing DPS for better ammo economy, as the Rotary Cannon can burn through money if not used with restraint

Special Credits to HeyHeyPay for finding this Stalker part: In the container buildings with all the guards, between the two bridges, you can find the TP 500 Coffin in the highest floor, a light stalker armor

Occasionally on the streets, NPCs with the Airsoft Gun will attack you, you can loot the weapons from them without risk. You can also find enemies wielding the Benedetta M6 in some of the apartment buildings.

On the first extraction point you will see the Bernardi Residence facing the park, you can destroy the locked door or backdoor with Stalker Weapons. The guards inside will carry the V16 rifle and the Benedetta B56 pistol.

Do the quest given by Enzo Bernardi and he will give you the safe combination 213, inside you will find the Bertilda 94R, an automatic pistol and my favorite secondary weapon for the early game, as while it doesn't have as many bullets as FM B90 it has much higher projectile mass making it easier to deal with armored targets, it also has a burst fire mode for better ammo conservation.

Across the Bernardi Residence, you will find a Park, the park has a ramp leading to a Bar, there you will find a strange character named Silver next to a dog, he holds the Rheinstahl MG52, a heavy machine gun and one of the best guns in the game. He is incredibly armored, particularly in the head as it has a helmet that seems invulnerable to bullets. Do not try to fight him with small arms, instead, I recommend killing the light tank that is nearby for the V167 Rotary Cannon, you can then pick that weapon and shoot him in the chest at point blank, this is the only thing I found that could kill him, just be mindful of the recoil. BEWARE THIS IS A QUEST NPC, you need him as in a nearby building a guy is looking for the dog next to him, complete that quest to unlock his helmet the Silver Total Protect helmet for purchase on the garage costing 20k euros.

On the Vermeulen Gate you will find a mansion full of heavily armed NPCs with FM B90s, on the balcony there will be a guard with the OSB-96, a sniper so powerful it can damage your mech with full armor. Kill him and the stalkers outside, then try to bait the guards to come out and clean the house.

On the bathroom on the first floor on the shower there will be a breakable hatch that leads to the sewers SEE SCREENSHOT, i highly recommend bringing the flashlight and night vision for this zone as its pitch black. Enemies here will have the HX SDAP5, a silenced submachine gun.
Keep progressing and you will come across a wooden bridge with boards leading down, depending on your health you might need the rope gun as fall damage might kill you. Across the bridge there is an intersection leading to a locked door you can break with a breach charge. Drop down the woonden bridge or go behind the locked door and you will start finding enemies wielding the HX B11, a flechette pistol

https://images.steamusercontent.com/ugc/40075427754230847/BC0FF23246C9C63E8C62377E631B22611DC0D698/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false

Had to made a part 2 for this zone as it is deceptively big due to the extensive underground system

STALKER PARTS:
The light tank in the street and the Stalkers inside Vermeulen Gate carry the V167 Rotary Cannon, probably one of the best Stalker killing weapons in the game especially in the early game, capable of even melting mech bosses, easier to grab from the light tank as it has low HP

Progressing through the depths under the mansion at Vermeulen Gate, where you find the HX B11, after dropping from the wooden bridge near the Depths extraction point, you will find the SEEB Mantikora 92, a light Stalker armor, inside a room with two flesh rats on the corners out of sight, do not use night vision here as the room for some reason is so bright with night vision you can not spot the flesh rats and they will insta-kill you even with the best armor since they poison you

https://images.steamusercontent.com/ugc/40075427754268337/6D638935D195BCA76D8355DB5EB34AEABF63810C/?imw=256&&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false

On the center of the map there will be massive towers belonging to a funeral home, guards on the upper floors carry the HX AP5, an unsilenced version of the submachine gun carried by the sewer guards on the previous map.

On one of the edges of the map you will find the Gym, with a pickup truck outside. Guards inside wear blue pants and carry the MR-37, a revolver similar to the one the detective has. They have no armor but the revolver can deal a lot of damage.

To get the Automag 7 follow the questline around the missing bodies (Memory is Precious), marking it as a spoiler in case you want to give it a go yourself. Talk to the funeral home receptionist, then talk to the grave digger Otto Schwarz, he is in the graveyard near an big digsite.

After that talk to the gym owner Bramby Maxim. Proceed deeper into the Gym until you reach a room full of hollowed heads, just before a trapdoor guarded by an unkillable zombie

Return to EPF offices and talk to the doctor who is next to Konrads Office, then return to the gym.
If you did everything alright Bramby should no longer be in the reception and all guards will be immediately hostile, he will be in the same room as the hollowed heads wielding the Automag 7, a .50 cal desert eagle. HE WONT RESPAWN but as far as im aware he wont deaggro and it is intended for you to kill him, but i might be wrong

Thanks a lot to Allie In Wonderland for finding this elusive gun: To get the secret 10mm variant of the HX AP5 you must do some extra steps during or after the questline around the missing bodies (Memory is Precious) so marking it as spoilers as well since its enjoyable detective work. Fight your way to the very top of the Necropolis Funeral tower, until you reach the floor with the bridge connecting to the other tower.

Break the armored door and read the info on the computer. Then go back down and exit to the graveyards. There will be a small wooden shack, near some graves and close to a white marble statue of a circular head somewhat resembling Konrads head. There will be a hidden trapdoor in the floor leading to a basement with a locked door with a keypad, the code is "HUMAN". After reading the info on the computer inside there will be a unique enemy right on the shack with a shotgun so kill him as soon as you see him when going back up.

Go back to the tower to the very top floor again and this time cross the bridge to the other side, be warned there are enemies guarding the tower with incredible accuracy so kill them from the other side if possible as there is no cover on the bridge. Inside the other tower room the receptionist of the funeral home will be there wielding the HX AP5/10, a 10mm variant of the HX AP5, making that gun the one with most variants in the game so far, with a total of 5

FOR THOSE WONDERING what's up with the trapdoor and the zombie and the weird entity on the sewers. SPOILERS

You need to be quick, drop down from the trapdoor after incapacitating the zombie and preferably killing the flesh rats from above, after dropping down there will be a secret stone door you can open, head right until you reach a wall and then keep going to the right, at some point the weird polygon will start pushing your screen to the left but keep turning right as hard as you can, you will reach a corridor with a big mutated flesh rat, do not touch it but kill it, after that the weird polygon will disappear, be careful as if you reload the zone it will respawn

STALKER PARTS:

Sometimes when loading in a small Stalker will appear, wielding the Parasonic 20mm rifle.

Thanks a lot again to Allie In Wonderland for finding the new Stalker legs: In the basement of the Gym in the room under the trapdoor guarded by the unkillable zombie where the flesh rats and the weird entity resides there is a new set of Stalker legs that was added with the latest update, the Seeb Manticora Booster-S

Guards in this zone drop the Minato M9 in case you didnt grabbed it outside the EFP HQ

Armed employees drop the SOG P337, an unremarkable pistol

In the area further into the map close to the big tower in the boss Stalker arena you can find guards wielding the V73 DRL, an antitank rocket launcher, it is capable of melting your Stalker but on the other hand it is also probably the best small arms against enemy Stalkers, sadly it only has 3 shots

Mowzer SP777 is a weapon tied to a side quest and somewhat to the main quest, marking it as spoilers in case you want to find out yourself


If you picked the Firearm Permit back on EFP HQ and gave it to the receptionist on the permits room the NPC on the room to the right of the Gaia lobby at the complaints office will wield a unique silenced Sniper Rifle Mowzer SP777
To get the Firearm Permit do the following:

• After Spawning in your office in EFP HQ, exit your office, go to the right and follow the corridor all the way into a 4 way intersection above the lobby, then head to the room inside the yellow and black stripped wall
  
• You will see a room full of cabinets, there will be some with wooden cabinets that are openable and breakable.
  
• Use the cabinet doors to make a stair so you can get atop the cabinets, lying atop the cabinet walls you will find a document called Firearms Permit

After you talk to the Gaia NPC right to the Gaia lobby and accept his small favor quest you can go back to the Cabinet room and talk to the receptionist there, she will process the permit and when you go back to Gaia the NPC will have the sniper rifle, you can now also enter most areas in Gaia Beauty without getting shot. If it wasnt obvious this is a Quest NPC so it wont respawn if killed, however after getting permission to roam around it seems it is safe to kill it for the sniper.

STALKER PARTS:

On the lobby spawn go to the left past two guards guarding a restricted zone, after exiting to the courtyard outside through a small opening look to the left and you will see the GHI EYE, a light Stalker armor

Thanks to wastrel strumpet for finding this out, when spawning into the Gaia Lobby, on the left to the lobby there will be a big glass door leading to two waterfalls, on the waterfall to the left you can go through it leading to a small parkour section containing the Rheinstahl CS, a medium Stalker core

Killing the boss Stalker in the arena to enter the CEO tower further down the map grants the Nihilophant AAS armor for purchase, a somewhat heavy Stalker Armor

Enemies freeroaming in this zone have a chance to drop the HX AP5S, a semi auto only version of the HX AP5 you can find in EFP Office, a direct downgrade considering the normal HX AP5 can be put in semi auto as well. Same stats damage and range wise but features a much slower fire rate even compared to the semi auto mode of the HX AP5

Across a ramp going down from the restaurant/bar in front of the Sovereign Bridge exit there is a bank, inside enemies will drop the HX AP5K Covert, a briefcase disguised version of the HX AP5 with armor-piercing rounds, capable of damaging even locked doors, although it struggles to break them completely

On the harbor on the sea there are some guards close to a very powerful Stalker holding the HX G12 rifle, a powerful scoped rifle that uses caseless ammo with high mag capacity


STALKER PARTS:
In the warehouses behind the restaurant where you find the SSR 3001 is the Stalker armor TP 1000 Grave, it weights only 100kg less than the EFP Heavy Armor but features 100 more armor points for a total of 1100, the highest I've seen so far but only 10% higher than the heavy armor, still a direct upgrade given the lighter weight and higher stats.

In the harbor on the sea in a corner of the map, close to the apartments with the cruiser Stalkers there is a powerful blue Stalker from the shipping guild, killing it will reward you with two powerful weapons, the GHI OAC, an energy weapon that uses ORGONE energy which excels at killing personnel and smaller Stalkers/vehicles, and the Ikon KIA, a 25mm automatic Stalker weapon with high mag capacity, perfect for Stalker on Stalker combat, it replaced the V167 Rotary Cannon in my Stalker as soon as i got it. Its best to snipe it from a distance as even with 1100 armor it insta-killed me a lot of times.

This is also a zone with a lot of weapons hence the part 2, most of these you can find close to the bank, on a slightly elevated zone with two apartment buildings (one luxurious and one not so much) guarded by opposing factions and small Stalkers. Outside in a ramp leading to the apartments there will be a guy in a car with a quest for you.

The guys in the courtyard wield RBK-47 a rifle with expanded magazine, and inside one of the buildings you can find the BK-47, the non-extended version of the RBK-47. Across that building inside the luxury apartments you find guards wielding the Steer BUG A1, a scoped rifle.

The Hyena is a High Explosive Armor Piercing Pistol, probably the most powerful pistol in the game, inspired by Alucard pistol Jackal from Hellsing most likely, it is also the only small arms I've seen that has a stat requirement, needing 35 strength to wield (your poor wrists). It is inside the Bank vault, to get there go to the left of the bank lobby, there will be a locked door with a keypad guarded by guys with briefcase guns, i recommend killing them all from outside before going in, as the armor-piercing rounds and high fire rate from the briefcase guns make them quite nasty, and as soon as you step into the vault zone they will become hostile.

The code to the door is just all nines "999999999", inside there will be a lot more guards, i recommend killing them all from the other side of the door, as further inside there is a turret with a minigun and a Vault Stalker. Kill the turret very carefully as it locks onto you instantly and rains bullets non-stop, thankfully it is very fragile.

Dealing with the Vault Stalker is quite easy since its so big it can not reach the room you're in, you can use the briefcase guns to kill it since there are so many lying around. There are two doors to enter the vault, the first you can open by clicking a button that looks like an eye in one of the rooms inside, to open the next door i recommend bringing a 25mm Stalker gun from your Stalker and shooting the door. It will break and inside in a pedestal you can pickup the Hyena.

Special thanks to PropagandaPanda for finding this out: In the bank there is also the first ORGONE energy small arms I've seen. It is hidden in the bathroom on the first floor of the bank, in the wall to the right of the reception behind a wooden door. Break the toilet and the wall behind it. A cube abomination will come out and shoot you with laser beams, kill it and it will drop the Ventman Organ, a really good gun as it has unlimited ammo as long as you have ORGONE energy and costs nothing to shoot, its only downside is it really struggles against armor.

STALKER PARTS:

Stalkers guarding the elevated apartment complex drop the Ikon 25mm Rifle, and the Mk25 Automatic GL

The GHI 13mm MG is tied to a very important side quest from the Bank Talk to the receptionist Moray Eel about becoming an accredited investor, he will tell you that to become one you need 15k euros in the bank and help him out with a debtor in the Versten Residential area named Udo. Go there and talk to him, then come back to the bank AND LEAVE YOUR STALKER RIGHT AT THE ENTRANCE. Talk to Moray, you will have to pay some money but after doing so he will tell you to come back later. Depending on where you are in the story you can bribe him and get him to talk about some characters in the main quest.

Go to the second floor of the bank and talk to the guy there, he will tell you he will make you an accredited investor after you figure out who Moray Eel is, as he does not recognize him as an employee. Moray will no longer be in the reception of the bank, he will be in a fairly powerful Stalker right outside, kill him and his Stalker will drop the GHI 13mm MG

No new weapons i could find in this area so far

STALKER PARTS:

Coming in through Versten Residential you will see a chopper flying in the distance, and what seems like a crashed helicopter on a hill, pick it up as it is a Stalker Heavy armor. Its stats are identical to that of the Rheinstahl VS-A but with a bigger hitbox, looks cooler tho

Progress through the zone until you reach the exit to the countryside, on the exfiltration point you will see a small hut, inside is the hammer, you can it take without issue

STALKER PARTS:

There are many stalkers here but they don't seem to drop new parts, haven't found anything new so far

Enemies roaming around will drop you the M87, a grenade launcher, the Obrez, a shortened version of the Mosin-Nagant, and the Mosin in case you didn't grab it when you first left the EFP HQ

On the dinner in the middle of the map you can find enemies wielding the Fobors CBT-ME, a submachine gun with a whooping 300 rounds total and decent damage, probably the small arms with the biggest mag size in the game, it only struggles against armor so aim to the head always

On the mansion belonging to Hannes Lunk close to the dinner you will find guards carrying the PaTiMatic, a submachine gun.

The Short-12.7mm is dropped by Rural Stalkers, it is a weird weapon since its both a Stalker weapon and small arms. It can be wielded with surprising ease unlike most Stalker weapons and has almost no recoil for a heavy weapon (with enough strength of course). Probably the most powerful automatic "small arms" in terms of projectile mass, but has a high cost per shot.

STALKER PARTS:

Rural Stalkers carry the V-Mosin-Nagant, and the Short-12.7mm

You can find the Tractor Armor inside a shed right to the entrance from the Bitter Gorge. Quite silly.

Close to the dinner, there will be a big Stalker carrying the Rheinstahl R-120, a Stalker weapon so powerful it will kill you if you attempt to shoot it on foot. It insta-killed my stalker at 1100 armor, so make sure to take the Stalker out as fast as you can, and don't stop dodging

STALKER PARTS:

Special thanks to Fax Machine for finding this very well-hidden part:

To get this part you will need fairly high AGILITY (around 50)

Get to the Hannes Mansion right behind the Service Station, on the top floor of the Mansion there is an office entirely made of marble, on the desk there will be a small marble cube you can pick up.

Go outside and climb the big marble pile between the marble house and the mansion, you will need a high jump height that you can get by leveling up your agility. Once you climb the marble pile there will be a hidden marble door you can open with the cube you picked up. Inside there will be a Stalker Part Carrara Marble Armor camouflaged as a marble cube

Enemies in this zone wield the M87 Riot, an M87 variant that shoots toxic gas grenades. CERN guards also carry the L-89, a 20mm caliber anti-tank gun.

Right after reaching this zone, in a house right in front of the first extraction zone, close to where a hostile dog is, you can find the Rope Gun in a window frame leading to a small fenced garden.

Special credits to Tabby 𓆩♡𓆪 for finding the next two items:

Some trees with platforms in the center of the map lead to a house on a hill, in front of that house (where the Residency Extraction zone is) there a big mountain with a clearing in the middle, in that clearing you will find quite literally mushroom men holding an automatic ORGONE energy weapon called Mycoprotein Artifact, pick it up, its really good as it costs nothing to shoot except for targets with armor.

Take the golden mushroom to the man in the Mushroom Farm, he will give you a key to open an indestructible door nearby, where you can find the Mushroom Hat, technically not a weapon, but a cool item regardless

STALKER PARTS:

Credit for this find goes to Fax Machine, thank you very much for your contributions:

From the mushroom extraction point head into an opening between two mountains directly in front of the farm, then go to the left and keep going to the left until you find a small Stalker guarding this part, it is partially submerged in the water. Its called the Coprogod, a somewhat heavy armor that is very creepy

This whole area is one big spoiler so be warned.

I recommend going all the way through the facility until you reach the core, talking to the old guy inside and then talking to Lorenzo in EPF HQ to "finish the game", as the CERN facility will come into your control, making it much easier to explore it as guards will no longer shoot you on sight

From the entrance of the facility, go through the small corridor on the right and follow it past a big sphere room with water in it, then go to the right into a room with 2 guards with Rheinstahl Machine Guns, there will be a room to the left with a ramp leading to it, inside that room you will find the SEEB Mantikora Frame

SPOILERS

There are 4 additional characters that are unlocked by finishing the game... duh

They are the CERH operative, the Mycoman, Celestial Prisoner, and the Cosplayer

Some of them have items that are impossible to get through a normal playthrough, such as the CERH Helmet, and the Mycoprotein Armor, some of them also just have straight-up busted stats, like the Cosplayer, that is almost level 400 and has 99 on all stats except on 2
