Minecraft creator Markus Persson (aka Notch) participated in this year's 7DFPS developer challenge, a week-long game jam centered around first-person shooters. Persson's entry is Shambles, a Unity-based shooter that drops players in the middle of a zombie apocalypse with 50 bullets and 100 health points.

Players don't just hunt zombies in Shambles, though, as soldiers drop weapons and civilians drop health packs when killed, turning survival into a balancing act. As with other 7DFPS games, don't expect Shambles to offers hours of entertainment, but it's a nifty way to pass a little free time.
