PS4 owners aren't the only one getting their Killing Floor jam on this month. For the next day and a half (June 22 - June 24), Humble Bundle is giving away the original game for free from their store. No other purchases are necessary; you just create an account, add Killing Floor to your cart and you're good to go.
I don't know much about the game, other than it being a chaotic co-op shooter, but I can't argue with free. I'm sure this will be a good way to generate interest in the sequel, which is currently rocking a 50% off discount in the Steam summer sale. Not too shabby.
