The Hungry Horde
You start the game off controlling a couple of wayward zombies. Every time you bite a human they join your ever-increasing horde, until you’re controlling whole streets full of the undead. Unfortunately, rampaging through the streets eating brains is always going to grab someone’s attention, and sensing the danger to the population the government has decided to do the only sensible thing they can: quarantine the area and nuke you. So it’s a race against the clock to gather a big enough horde to smash down any human defenses and take on armed guards, tanks and any other opposition that gets between you and those tasty brains.
