It's just monotonous as hell. You have to kill 50,000+ zombies in one game. Your best bet is to head to straight to the tunnels and run them over for a few hours. It is a real pain, because you will go through a lot of vehicles. And they'll often die at the worst possible moment, leaving you in the middle of a zombie swarm. I still have nightmares!
