It's pretty neat, you can choose to be a Tranformer version of several different Chevy models, unfortunatey there are no Hummers (not even a Corvette either.) Each model has different strengths and weaknesses and you can upgrade your abilities by solving codes (haven't figured them out yet.) It isn't live action though, you challenge someone then choose 5 attacks to use. They choose their 5 attacks and then the game decides who wins. I'm tanklizard and right now I'm 4-1.
