Even if the second part is already available I decided for this item. Was a flash offer here at Amazon.
I keep it short because there is already enough reviews.
Huge game scope. Especially with all the extensions.
Again and again, better, stronger and more cool weapons!
Very nice coop mode. Also via splitscreen.
Although missions are often similar but what else I expect in such a game is not really.
Opponents adapt to the level. So is not too boring when you're running through already known areas.
All in all, very cool!
