This game is awesome. I'm about 8 hours in and loving every minute. After reading some reviews, I was dubious about buying it, but took the risk and it was completely worth it. Good story, engaging and addictive gameplay, great weapons and customisation. You can also develop the map and the city the way you want, depending on which factions you choose to support. A really great addition to an already fun game. If you like zombies, action and tactical play/decision making, this is the game for you.
