As far as time killer’s go, Killing Floor 2 is one that I keep revisiting. The large variety of maps, variable difficulty levels, and randomness of enemy spawns gives this cooperative multiplayer shooter some thick and veiny legs. So, having it as the “early adopter” title in next month’s Humble Monthly package is a cool deal. Honestly, that game alone is worth the $12 dollar asking price. Anyone that likes their games gory and chaotic would do well to grab this one sooner rather than later.
