Hopefully you've already heard about Zombie Playground, the art-turned-kickstarter-turned-game featuring yet another fresh take on the zombie apocalypse that actually feels fresh. Massive Black's game will pit grade-school kids against the shambling dead.
This gameplay is... well, it's rough, but it's also pre-alpha, and mostly intended to give a sense of the basic game. Unclear whether the current soundtrack is Aesop Rock, but he'll be providing the soundtrack for the final game. Which is very cool.
