A must have !

EDIT: Killing Floor 2 is now fully released.

I've been playing Killing Floor for years and it is without a doubt one of my favourite games here.

+ The combat and carnage is unparalleled: explosions, dismemberment, and headshots look and sound great
+ The class and perk system is incredibly robust: classes have unique roles, pros/cons, levelling is addictive
+ Huge variety of weapons and maps adds a ton of replayability
+ Best free seasonal updates of any game out there

Fair warning, this is a skill-based game and it is difficult. Newcomers should start on Normal difficulty to learn the ropes and have fun. Playing on Suicidal and Hell On Earth requires a lot of experience, working as a team, and in-depth knowledge of game mechanics. For many people however - myself included - this is the real draw of the game. If you put in the time, playing on HoE with 5 other experienced players all working together is some of the most fun you can have online. There is also nothing more exhilarating than being the last one alive on Wave 10 knowing your entire team is watching and relying on you to stay alive.

Highly recommended.

Don't usually comment or write reviews, but when a game is this old and still brings out free content u have to give them credit, in today's sad monetized gaming industry of Season passes, online passes, launch day dlc, early access, etc.

I got into KF pretty late, around couple yrs ago. The first 5 mins I thought this is the biggest pile of crap I've ever purchased. Graphics are ugly, wave after wave in the same smallish map?!?! Why on earth are ppl still playing this game? I put it in my trash list.

The following day I had a strange urge to try it again, for whatever reason I don't know. I soon realised this game is not about arcadey run n shoot n regen health bs. This game's depth is about u as a team player and improving yr skills to take on bosses and tight situations. Reading the danger signs, when to run when to hold ground. You won't suddenly level up and get a powerful weapon, u only progress with improving yr gameplay.

The weapon mechanics are simply amazing. WARNING: after playing with no aim cursor and using only ironsights all other cursor games will suck.

Then there is the community made content. More guns, maps, zeds, bosses.....I have over 1500hrs entertainment time and I only paid $5. I think I bought some dlc just to support devs but its not enough for what they've achieved. I don't usually buy newly released games, the ones I've bought I've regret. But when KF2 comes out....just take my money, take it. Please.

TLDR: Buy the game. There's not many devs that care about their product.

In my 40 years of video game experience I feel Killing Floor is one of the best FPS games ever made.
The depth of the game is great. As much as the game focuses on multiplayer and teamwork and the game shines in those respects.. the solo side of the game is perfectly balanced to make it a great experience also.
As you progress in difficulty the money gets less and it becomes harder to make sure you have the weapons you need when you need them, but as you progress in level your weapons become cheaper and more powerful. The enemy is varied and as you get in higher difficulties you need to develop the tactics to take the tough ones down safely. Many tactical skills can be employed beyond defending one area and who is best suited to kill what depending on choice of class. Situational tactics like target priority and when to run and how to "kite", knowing when you come round a corner to come face to face with a crowd of enemy, just what ones you want to smack once and keep going, kill outright or just keep on keepin' on. Add to that an active modding community with extra maps, game types, mod weapons, games and modded monsters... free for download.
Not that you have to play it that serious either, many people just find a level they are happy with and just kill stuff for fun... that is one of the great things about the game ... you can play it at any level you desire, but the challenge is there if you seek it.
Things I see as a big plus.
NO PvP - you will not get "spys" or cheaters spoiling other peoples fun. There is one modded game type GunGame that is Player vs Player, but the normal game dose not.
NO set enemy spawns, in games like some of the ghost recon type games, splinter cell types is that once you figure out a way it gets boring and tedious. This game is a complete open environment and the enemy can spawn just about anyplace in relation to player position, so even a game played the same way can have different combinations of enemy at any one time.
For reference, other games I consider top notch FPS - Unreal Tournament, Quake 3 and Team Arena, BF2142 I consider Killing Floor better than them all. 2000 hours in 6 months speaks for itself.... along with 600 hrs in the free SDK making new maps. If you like FPS and don't own it, you owe it to yourself to get it. I have spent $1000's over the years on games that were little better than drink coasters... the money I spent on this game has been the best entertainment value of my life!!

edit - as of Nov 2015 3000 hours in game and 2000 hours in the SDK with 36 workshop submissions, most of those original new maps. An additional 1000 hours on alt accounts for map testing. Even with KF2 out this game is still well worth getting!

Nov 23 2016 Nominated for "Test of Time" award.

After playing a total of 126 hrs, I could honestly say this is my favorite zombie FPS style game. The game is incredibly fun and takes strategy to master, especially when attempting to play on the Hell on Earth difficulty. New weapons and free maps come out frequently which help keep the game interesting but being charged to own the latest and greatest weapon packs can be a bit of bummer.. Like all zombie based games, it tends to become repetitious. Luckily, having the option to increase the difficulty, play objective modes, and strive for seasonal achievements gives players more challenges/options to keep the interest in playing alive. If I had to rate the game, I would rate it a 9.5/10. Would bang.

Good Game!

Bloody great fixed and revamped retail version of the UT2004 Co-operative survival horror mod developed back in 2005. Set in possibly near future, in London, where a military contract project to create super soldiers goes wrong and the unfinished clone mutants have laid waste to everything in their way..
What's good:

The gunplay..oh MAYN the gunplay. Excellent gunshot noises, they sound simply such that they never get old, there's sharp reports and then there's more pew type for some weapons, all sounds fit their weapon. Also reload sounds are nice, almost no stock sound effects, and even where there is those, they are modified so it's fine with me. The TWI made reload sounds are great, not any overly sharp or crisp cheesy clatter etc..Also animations are fluid, the weapons have a fittingly harsh recoil, not realistic yes but who the f*** wants realistic guns in KF? Also the weapons shake your vision nicely, gives a nice harsh physical feedback into firing your guns..alright let's not write a book.

The Zed Time feature, randomly a slow-motion kicks in that lasts for a couple of seconds, lets you see them nice gun animations in detail, Specimens getting their limbs torn, heads popped and with demolitions slowly seeing how they turn to red paste..also it lets you catch a grasp accurately on what's going on around you, you can look around a bit to think what to do once the game speed returns to normal.

Specimen visual designs and their behavior, all of them have some kind of purpose to help and murder those damn survivors for once. They look suitably scuffed, grimy and some a bit grotesque and quite intimidating. Some of them are still pretty much human but others are full on cyborg mutants and have proper body horror and look disfigured. So their behavior then..so as I said all of them cooperate with their complementary to each other tactics, for example Clots aren't that bad even in groups but if they grab you you're in for a bad time because the bigger muties can get to pummel and bash you unhindered or simply a swarm of lesser specimens might overpower you. And Husks prevent players from being safe by simply staying away..those ♥♥♥♥ERS will no doubt at some point remove a good chunk of your precious armor and deal over the course of a few seconds a moderate dent to your health. Bloats can massively impede a readily panicking player from aiming properly and seeing what's going around themself. Crawlers often finish a lone terminally injured player who was just about to get some distance and continue fighting.

Great level variety, some of them almost solely outdoors maps, some a good 50/50 mix of outdoors and indoors, both viable camping areas. Also there are night time, evening etc maps and some with quite somber weather. Some have very nice vertical axis variation too!

-Proper weapon variety in each class, in some classes though it's rather damage per second difference vs. one shot damage. But a weapon with high DPS vs one hit power suits some purposes better.

-Pretty good gore system for being in 2004 era game engine. Same gore effects apply to both players and the specimens I may add. Dismemberment can happen, at the limb joints and of course neck, leaving visible bone and roughly torn flesh and blood spraying too. The next level of gore is that a specimen either loses half of all his limbs or simply gets turned to small chunks and red mist which looks endlessly satisfying as a Demolitions. So yeah pretty nice gore, it can be quite terrifying to see your player get torn to pieces by a Fleshpound's pummeling.

-Raw soundtrack, most of it badass Industrial by zYnthetic, and then a smaller bunch of action tracks are more standard metal. Fuels your rampage suitably. At downtime there plays some well done ambient music, pretty much all of it too by zYnthetic.

What isn't good..

-Removal of the great weather effects and ambient sounds in the maps Westlondon, Manor, Bioticslab, Offices. In the mod version 2.5 atleast, these maps had amazing atmosphere.

-The slight lack of voicepack variety, could have been like 4 different voices or so. I do like the voice acting though, it's silly and not all too good but in a charming way.

-You can't disable Trader's lines while still keeping the random player chatter on..

You kill zombies, but no floors.

1/10 the devs lied
