I saw some zombie simulators out there, and they were pretty cool! However, without anybody to fight off the zombies, you could always predict the outcome of the simulation --- the zombies will infect everybody. Along with that, zombies could only infect! To improve this, I added hazmats. Hazmats are tough and hard to kill. Their electro-staffs do extra damage to zombies. With hazmats controlling the infection, who knows what will happen?
