The Battle of Polytopia (for iPhone)

Each tribe has units and buildings unique in appearance, even if they have stats identical to other tribes.

The game comes with four playable tribes, with more available for 99 cents a piece.

You begin the game with a single unit and a single technology. Which unit and technology depend on the tribe you select.

Research new technologies to unlock new units and buildings.
