The indie project Land of Zombies has been released on Android in all countries. You take on the role of a soldier, who must deal with the soldiers and get the vaccine.
Land of Zombies is a zombie shooter available on Google Play; no information about the iOS version. You will have to clear the locations of a plague-stricken metropolis. The plot is simple, but interesting for a game of such a small scale – one researcher almost created a vaccine, but did not have time, because zombies broke into his lab and ate him; you have to find the drug and escape.
Land of Zombies even has voice acting – you talk over the radio to another soldier, and you both have voices from India or even Africa. The developers have also added cut-scenes on the game engine. If you want to get coins for powerful guns, you have two options – to kill zombies or watch commercials; you can combine the two.
In addition to completing levels, Land of Zombies has a zombie-mode-type fending off waves of the dead in the Call of Duty Black Ops series; the developers even added ammunition crates, but everything takes money.
