Take command of squad in an infected zone and make sure that they fix their vehicle before the zombies overwhelm them. Order your soldiers to perform tasks, such as looting, healing and reloading. Your squad will have to deal with waves of the zombies as they perform these tasks. Soldiers will automatically shoot zombies and reload their weapon when they run out of ammunition. Looting boxes and killing zombies gives you money, which can be used to recruit soldiers and purchase new equipment. In addition to equipping your soldiers with items, you can upgrade their skills as they level up.
