Get Killing Floor for Free Until June 24th on Humble

If you're looking for a co-op survival game to play with your friends, look no further! You can pick up the original Killing Floor for free from the Humble Store. While Steam's sale is the highlight of this week, the Humble FPS Sale is also going down right now. Killing Floor may not be the newest title around, as it came out in 2009, but it's free!

The game features a ton of blood, weapons, and zombies, which is perfect for a co-op survival game. You really can't have a zombie apocolypse title without the big 3 I just listed, and with DOOM-style blood and gore, you'll have a pretty good time. You can check out the Humble page for the game right here!

Another key aspect to keep in mind is that just about anybody can run this game. I mean, this game came out before Left 4 Dead 2, which feels like decades ago in the gaming world. If you have a PC that can open Google Chrome, I'm sure you can run this game! Check out the gameplay trailer down below and see if it's something you would be willing to download for absolutely no cost! Be quick though! The free version of this game only lasts until 1 p.m. EST on June 24th!
