Glu mobile has published a single screenshot of their upcoming original Transformers game for iPhone.
Judging from single screenshot, the game is a polished port of an already released mobile game of the same title.
The gameplay has a similar style to that of the Advance Wars series for Gameboy Advance and Nintendo DS. I would call it a turn-based strategy game with sweet battle animations depicting the battles.
You can try out Glu’s mobile version on their free trial web-based emulator.
