Killing Floor is a popular, low-cost alternative to the Left 4 Dead series. Its 6 player online co-op and addictive character leveling system more than compensates for the absolutely haphazard character and monster design. The Steam game goes on sale constantly, which has helped it reach its millionth sale recently. And what better way to celebrate than another big sale?
From now until Thursday, Killing Floor is on sale for $2.99, down from the regular price of $19.99. A bundle with all of the character DLC costs just a smidge more at $4.78. If you're looking for an affordable multiplayer shooter for PCs (with fairly low system requirements), give this deal a shot. And don't forget to check out our co-op review for more gameplay details.
