The series has been one of the few mobile games that stands out for its quality gameplay. To keep S.A.S. Zombie Assault 4 unique, Ninja Kiwi has taken a new setting.
SAS Zombie Assault 4 is a new zombie shooting game for the iOS and Android, as well as for other platforms such as Kongregate. Your goal, just as with the past four SAS games, is to shoot up massive amounts of zombies while avoiding getting killed, in order to protect a specific area, or simply to play against other players.
Probably one of the few free to play mobile games that dosn't suck or try to milk players for nickles and dimes.
