Perks were added to the newest update for the iOS version of SAS: Zombie Assault 3, and they are exclusive to this version as well. Perks give the players an advantage in-game by giving them special abilities and enhancements for their character. They only last for the duration of one game however. Before entering any game, the perk selection screen will appear, which is where you can spend in-game money to activate any number of perks. The effects of some perks are stackable. This means that in in Co-Op mode, if any other players have purchased the same stackable perk as you, the in-game bonus of the perk will be multiplied accordingly.
