Different game types exist in the form of objective and survival modes. In objective mode, a randomisation system is used to create different branching objectives for each game to enhance replayability. Survival mode sees the players defend pre-determined safe zones from waves of zombies while also fighting to stay alive. Each wave becomes increasingly more difficult, with more zombies in each wave and with more dangerous zombie types such as runners and burning zombies added to the mix.
