City of the Condemned (CotC) is a succesful Seven Day Roguelike Challenge 2010 entry. The game depicts a battle between angels and demons in a randomly generated city. The goal is (depending on the side) to either protect or destroy the humans. Victory can also be achieved by vanquishing the opposing force or ascending beyond archdemon / archangel status.
