“The multiplayer in this game is not the best, i couldn't even connect with my friend. If your buying this to try it out with a friend, its going to get annoying”
“One of the game I've spent my childhood with. Basically better than Killing Slop 3, and even Killing Floor 2 in term of atmosphere and vibe. I'm Asian so ofc my ping will be choppy in many servers but I'm just glad to…”

“Forgot to give this game a review, so here it is. At the time it was amazing, awesome game and awesome community that made awesome mods. The game is really dated now, so i dont really recommend that you buy it, but if…”
“Amazing game, aside from its age and spotty voice acting in a few places. Good balancing, harsh difficulty, decent shooting, overall it's a pretty nice game, but I certainly wouldn't suggest you buy it for 20 USD, it's…”

“Killing Floor is criminally underrated, and the fact it’s basically half-dead now is just embarrassing. This game does co-op survival better than most modern shooters and still gets ignored while people go play watered-down garbage. No hand-holding, no cinematic babysitting—just…”
— a player, Steam review · 15 hrs played“I came back to Killing Floor after trying a lot of modern shooters, and it still has that raw, tense co-op vibe that’s hard to replicate. The atmosphere is darker and more grounded than most wave-based games, and when things start going wrong, the pressure feels real. Each perk…”
— a player, Steam review · 31 hrs played“It is insane how fun this game is but there is a huge issue with servers being DDOS'd and it's bene happening for a long time while tripwire has done NOTHING to help with this issue. still I highly recommend this game over KF2 and especially KF3 as you can make your own mods…”
