Survival horror meets real time strategy as you command marines against the undead hordes!
In MISSION mode, you must complete a sequence of missions. These have different tasks, such as finding medical supplies, rescuing civilians, or simply taking out some of the undead horde.
When the mission is complete, find the extraction zone and hold tight until the chopper shows up.
Any squad members that die in a mission will not be available for the next one, so keep as many men alive as possible.
In SURVIVAL mode, you just gotta kill as many of the undead as you can before they eviscerate your crew.
