There aren’t too many action games to be found on social gaming platforms, but GREE has Destroy Gunners, a 3D action game for GREE on Android that actually looks pretty good (I myself didn’t have the time to play it yet though).
In the game, players control two-legged robots, destroying other robots and bosses at the end of the levels.
Here’s the link for the free download on the Android Market (where Destroy Gunners has been downloaded between 10,000 and 50,000 times already).
