It's basically of a high-scoring mini-game-ish type. Tilt to move left or right, touch on the screen to move your crosshair and fire (crosshair will always be a little to the right of the spot where you touch), and there's a switch weapon button.
There's only 2 weapon types, Missile and Machine Gun. Guns overheat, and Missiles are on cooldown in between shots.
Has achievements, but no Game Center.
I guess it's a decent high-scoring game, but the lack of Game Center hurts it a bit. Oh, and no device auto-rotate. GUI also needs a lot of work. :P
Animation when moving looks silly coz your mech's body is like floating through the air while the legs do everything. Nice how the mech turns when strafing through.
It's decent, but it wont scratch that "iOS-mech-game-itch."
