If you’ve always wanted to slay mutated hordes in the English capital then Steam’s Midweek Madness deal will scratch that itch. The deal is over £4 better than the next best alternative, but if you want to get hold of all the extra character packs you can get the complete bundle for £3.21, which is still a saving.
Killing Floor is a co-op multiplayer FPS that is essentially one giant horde mode where you and your team fend off against increasing numbers of mutated “specimens” before engaging in a boss fight. As you survive you earn cash that can be spent on improved weapons and perks allow you to customise your style of play in an understated and enjoyable co-op FPS. Thanks to 5867dude @ HUKD!
