Different, but a waste of time.
Its a post apocaliptic world and you get to slap weapons on vehichles (mostly tanks) and blow stuff up. That should be a really kool theme for a video game and in the beginning it is. But as you progress and get stronger so does the forces you fight against until at the very end they are slightly stronger making battles difficult.
In the end the game doesnt really offer anything worth remembering. The battle system is your cut and dry menu driven combat system, the kind that put you to sleep. There are no cool minigames. Theres a hard cap on stats and vehichle strength meaning there really isnt much to do after you reach that point.
In the end the novelty will wear off and you will be left with the feeling that you just wasted alot of time on nothing when you could have been playing something better.
