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.
This guide covers everything you need: core mechanics, the best characters, weapons worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Wave structure and boss wave
Matches run Short at 4 waves, Medium at 7 or Long at 10, and every length ends with a boss wave. The boss is picked at random from Hans Volter, the Patriarch, King Fleshpound, the Abomination and the Matriarch.
Zed Time
Kills carry a chance to trigger a short slow motion window, with better odds on close kills and on headshots at range. Every perk gains a Zed Time skill at level 25, and Commando is the one perk that can extend the window more than once.
Trader time and dosh
Between waves a trader pod opens, everyone is healed to full, and you spend dosh on weapons, armour, ammunition and grenades. Dosh can be handed to teammates, which is how a squad arms its Field Medic on wave 2.
Perk levelling to 25
Each of the ten perks levels separately and offers a choice between two skills at levels 5, 10, 15, 20 and 25. Levelling a perk means using its own weapons, so switching perks mid session restarts those damage bonuses from nothing.
Weapon weight limit
Every weapon carries a weight value against a limited carry capacity, so a loadout is a budget rather than a shopping list. Off perk weapons cost the same weight while giving none of your perk's damage bonuses.
For a deeper dive into how these systems interact, see our Killing Floor 2 combat guide.

Weapons Guide
| Weapon | Why It Matters | Best For |
|---|---|---|
| AA-12 Auto Shotgun | Support's top tier automatic shotgun, able to erase a pack of Clots or strip a Scrake at close range. | Holding a doorway on Suicidal and Hell on Earth. |
| M14 EBR | The Sharpshooter's semi automatic rifle, accurate enough for headshot decapitations from one side of a map to the other. | Killing Scrakes and Husks before they close the distance. |
| RPG-7 | Demolitionist rocket launcher with enough single target damage to stagger and finish a Fleshpound. | Boss waves and Fleshpound heavy spawns on Long matches. |
| Zweihander | A heavy two handed sword for Berserker with the reach to hit several Zeds per swing and the block to survive a bad position. | Berserkers kiting large Zeds away from the rest of the squad. |
| HMTech-401 Assault Rifle | The Field Medic's high tier rifle, firing healing darts alongside normal rounds so the medic still contributes damage while topping people up. | Medics who need to hold their own from wave 8 onward. |
AA-12 Auto Shotgun: Support's top tier automatic shotgun, able to erase a pack of Clots or strip a Scrake at close range. Ammunition is expensive, which suits a perk that resupplies itself.
M14 EBR: The Sharpshooter's semi automatic rifle, accurate enough for headshot decapitations from one side of a map to the other.
RPG-7: Demolitionist rocket launcher with enough single target damage to stagger and finish a Fleshpound. Explosive friendly fire is real, so it needs a lane of its own.
Zweihander: 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: The Field Medic's high tier rifle, firing healing darts alongside normal rounds so the medic still contributes damage while topping people up.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Burning Paris | Any difficulty, ideal for learning | Reliable choke points, short trader routes |
| Biotics Lab | Hard and above | Strong door holds, compact layout |
| Outpost | Any difficulty | Sniper lanes, defensible interiors |
| Black Forest | Hard and above | Multiple fallback positions |
| Nuked | Suicidal and Hell on Earth | Open kiting circuits, long firing lines |
Burning Paris: A wrecked Paris street from the game's launch lineup, with a handful of strong interiors and long open stretches between them. The map most teams learn the fundamentals on.
Biotics Lab: Tight laboratory corridors where Support welding and Berserker blocking both pay off, and where a Siren scream is far more dangerous than usual.
Outpost: A snowbound military base with long exterior sightlines and cramped interiors, rewarding teams that can switch between kiting outside and holding inside.
Black Forest: Wooded German setting split across several separate buildings, which makes getting isolated easy and rejoining the team much harder than it looks.
Nuked: An irradiated test site with wide open ground. Maps like this punish slow perks and reward anyone who can shoot while walking backwards.

Tips That Actually Matter
- 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.
- Scrakes are a headshot problem and Fleshpounds are a stagger problem. Decapitating a Scrake with an M14 EBR or a Gunslinger revolver removes it outright, while a Fleshpound enraged mid corridor kills whoever happens to be closest.
- Zed Time triggers more often on long range headshots and on kills within about three metres, so the way to see more of it is deliberate shooting rather than spraying. Commando is the only perk that extends the window repeatedly.
- Everyone is healed to full at the start of trader time regardless of how the wave ended, which means the last few seconds of a wave are never worth dying over. Plan the purchase before the wave finishes.
- Dosh transfers between players. Giving the Field Medic 400 dosh on wave 2 so they reach the next HMTech weapon pays back across the whole match far better than the same money spent on your own upgrade.
- Sirens scream, and the scream destroys grenades, rockets and player armour at range. Kill them with hitscan weapons first and never point a Demolitionist projectile at a group that contains one.
- Weld doors during trader time, not mid wave. A welded door funnels spawns into a route your team already covers, and Support welds faster and stronger than any other perk.
- Off perk weapons still cost weight but lose your perk's damage bonuses, so carrying a favourite from another class usually makes you weaker rather than more flexible. Spend that weight on ammunition and armour.
- Boss selection is random between Hans Volter, the Patriarch, King Fleshpound, the Abomination and the Matriarch, so keep a full magazine of your heaviest weapon in reserve for the boss wave instead of burning it on trash.
- On Hell on Earth the team has to kite rather than hold. Large Zeds arrive in groups from wave 5, and a static squad in a small room ends up surrounded by Fleshpounds with nowhere left to fall back to.
Common Mistakes to Avoid
- Skipping armour to save for a tier 4 weapon, then dying on wave 5 with full pockets.
- Firing a rocket into a group containing a Siren and losing both the projectile and the damage.
- Enraging a Fleshpound with body shots instead of waiting for a clean stagger.
- Wandering off alone on open maps like Nuked where nobody can cover you.
- Levelling a fresh perk on Suicidal, where the damage bonuses you have not earned yet get the team killed.
Frequently Asked Questions
How many players does Killing Floor 2 support?
Six in standard co-op, across Short at 4 waves, Medium at 7 and Long at 10, each finishing with a boss wave. Versus Survival lets a second team play as the Zeds instead.
Which perk should a new player start with?
Commando or Support. Commando clears small Zeds and reveals cloaked Stalkers for the team, Support holds doors and resupplies ammunition, and both stay useful while you learn Scrake and Fleshpound timings.
What is Zed Time and how do I trigger it?
A random slow motion window that fires on kills, with better odds on close range kills and long range headshots. Every perk gains a Zed Time skill at level 25, and killing during the window can extend it.
How do I kill a Scrake without dying?
Decapitate it. A Sharpshooter with the M14 EBR, a Gunslinger with revolvers, or a Berserker parrying it in a corner all work. Body damage simply enrages it and sends it sprinting at the nearest player.
Is Killing Floor 2 still worth playing?
Yes. It still has populated servers and seasonal events years after release, and Tripwire supported it with content updates for most of its life. Killing Floor 3 now exists too, so expect the community to be split across both.
