Same old levels, same old guns, same old enemies, then..back again.
The graphics are good as is the size of the environment your in. The Needler weapon is a neat device. The ability to get into vehicles and use them to move around and destroy enemies.
The same old enemies on loop. The lack of variety of weapons. The tedium of seemingly advancing but seeing the same old scenery again and again, then having to do the whole lot in reverse as you try to escape from the monotonous levels.
The Bottom Line
Good Co-op and multiplayer but as a single player game it is very weak. And boring.
