There are typically between four and seven missions per game. Information such as times and days of the missions are released through the Groupspace.

Missions are not mandatory, but may provide valuable rewards for both human and zombie players such as innoculation tabs, cure cards, and reset feed timers.

Sunday will be the 'final' mission, in which any remianing players will make a final stand against the zomvie players to determine if the humans could survive throughout the end of the game or not. Should the humans fail this mission, zombie players will with the game. If humans successfully complete this mission, then they have won the game.
