How could we have missed this? Thank god for Alehkhs over at TIGSource, otherwise I would've never heard of Survival Crisis Z. A mixture of arcade action and traditional role-playing sensibilities, you play a man trying to survive the zombie apocalypse however he can. It has everything from sandbox gameplay to a living city. The city is even procedurally generated! Talk about replayability. There hasn't been a game that has drawn us in this much since Dwarf Fortress. It's an excellent game and well worth playing. You also might know the developer, James Silva, as the man behind one of XNA's stars, Dishwasher.
