Viscera Cleanup Detail still cracks me up
The impressive effort of a game jam, Viscera Cleanup Detail is another one of those inherently funny simulation games that's actually in on the joke. As you've hopefully heard by now, it stars you as a determined janitor who must clean a space station post-alien invasion. It's a bloody mess and for once we're the ones who have to deal with the gory consequences -- using the world's goofiest mop, no less.
Developer RuneStorm was surprised by the response the game got so it spent another week to add in co-op support, a common request among players, as well as two additional maps. You can try Viscera Cleanup Detail alone or with a friend by downloading the free alpha prototype. If you like what you see, there's a Greenlight page to upvote and a $5 pre-order to consider.
