The game is an absolute blast! One can even play with 2 players and even my girlfriend wants mitzocken. Gehts even better? ;)
At first I thought it is (after a few youtube videos) always the same. Make items broken, assemble, draufschlagen, finished.
But if it is by no means. You get always new characters and their abilities, so it does not become boring. Now have I think six hours played and I am impressed that you even have a free walk-city available between missions. Since coming GTA feeling on!
