Killing Floor 2 is Tripwire Interactive's wave based co-op shooter for six players, fighting genetically engineered Zeds across Short, Medium and Long matches. Ten perks level independently to 25, each offering a skill choice every five levels and a Zed Time ability at the top. Zed Time is the hook: kills randomly drop the world into slow motion while you keep moving at full speed.
Your choice of weapons defines your damage output and playstyle. This guide ranks every major option, explains what makes each one strong, and tells you which builds they pair best with.
Weapons Rankings
| Weapon | Tier | Best For | Notes |
|---|---|---|---|
| AA-12 Auto Shotgun | S | Holding a doorway on Suicidal and Hell on Earth. | Support's top tier automatic shotgun, able to erase a pack of Clots or strip a Scrake at close range. |
| M14 EBR | A | Killing Scrakes and Husks before they close the distance. | The Sharpshooter's semi automatic rifle, accurate enough for headshot decapitations from one side of a map to the other. |
| RPG-7 | A | Boss waves and Fleshpound heavy spawns on Long matches. | Demolitionist rocket launcher with enough single target damage to stagger and finish a Fleshpound. |
| Zweihander | B | Berserkers kiting large Zeds away from the rest of the squad. | A heavy two handed sword for Berserker with the reach to hit several Zeds per swing and the block to survive a bad position. |
| HMTech-401 Assault Rifle | B | Medics who need to hold their own from wave 8 onward. | The Field Medic's high tier rifle, firing healing darts alongside normal rounds so the medic still contributes damage while topping people up. |

Weapons Progression Path
The order you should acquire weapons as you progress:
- Starting gear → Enough to clear Burning Paris
- M14 EBR → Your first real upgrade, available early
- RPG-7 → Mid-game upgrade with good scaling
- AA-12 Auto Shotgun → Best-in-slot, aim for this by late game
- Upgrade to max → The power spike from max upgrades is enormous
Weapons Tips
- Always upgrade your primary weapon before diversifying. One strong option beats three mediocre ones.
- Match your weapons to your build's stat priorities for maximum scaling.
- Armour is the cheapest survivability in the game and it refills every trader. Buying a full armour bar before upgrading a weapon keeps more players alive through wave 7 than any single tier 4 purchase does.
- Check our tier list for how weapons rankings affect overall build effectiveness.
