Personally I would like to suggest a rescue scenario. Whether its a set number of days survived (400+) or total Z's killed (20k+) or both this triggers a new radio message on the emergency broadcast. The broadcast provides a criptic military message giving coordinates to a random location for a LZ. Obviously the LZ is crawling with undead. The survivor has to reach these coordinates at a certain time and date or has to wait for the next message several weeks later. Before the survivor can enter the helicopter needs to be dressed in military uniform and aquired an ID card from a dead soldier/location/vehicle. If he has not completed these tasks he will be shot as an infected.
