Campaign. This mode is based on the campaigns from Left 4 Dead. The player has to go the way with the remaining living people, and shoot back from the crowd of zombies. At first, you will have to fight alone, but during the course of the campaign you will find other survivors who will help you in destroying the zombies. At the end, there will be a special survival moment in which the survivors are forced to survive until help arrives. Campaign Features: The player is given the choice to choose a gun or a micro uzi at the start of each campaign. Among the infected are not only zombies. There will also be a witch and a tank.
Survival. In survival mode, you will be taken to one of five unique locations throughout San Andreas where you will face endless waves of zombies. The wave contains about 20 zombies, each wave of zombies will be slightly stronger than the previous ones.
