3. Gears of War 2
Pre-order Bonus: A radio controlled Centaur battle tank.
A Centaur battle tank! This steroid raged dune buggy was given away with the release of Gears of War 2 and much like its plot, couldn't hold much water.
Apparently, being the most playable title in the Gears of War Franchise (if you don't mind wincing at dialogue and more cut scenes than needed) wasn't enough for the little Centaur that could. Couldn't is more like it. The Centaur couldn't turn its wheels or get over carpet and fans were forced to tape it to the top of their Roombas and cry quietly into their own arms.
