This IS the droid you are looking for:
You play as 'Alpha Prime', the leader of the Go-bots (a team of sentient robots that can transition their bodies physically to appear either humanoid or as a vehicle).
Alpha Prime's 1st directive is help the people of Earth and to protect them from the sinister organization of Cobra.
Only you can save humanity in it's darkest hour.
Earth needs a hero, he's gotta be strong, and he's gotta be fast and he's gotta be fresh from the fight.
Earth is holding out for a hero, 'til the morning light, he's gotta be sure, and it's gotta be soon and he's gotta be larger than life.
Help us Alpha Prime, you are our only hope.

Nah dawg, I'm buggin'; there's no robots. It's just a standard space shooter from 2007 that has not stood the 'test of time'.
No Steam cards, no Steam achievements, no multiplayer, and chances are a bot wins this game key anyways.
But, should you enter and win...you'll probably kill a couple hours playing it trying to decide if you like it or not (if you still can't decide after 2 hours, I will refund your money).
