There’s some bad news for Halo fans out there who own a 4GB slim Xbox console. Reports are going around that the 4GB version of the console isn’t able to play co-op in the newly-released Halo: Reach as the console doesn’t have enough storage to fit the game. When a user with this version of the console tries to join a co-op campaign, they’re presented with an error message, reminding them that they will need an Xbox 360 Hard Drive in order to play co-op. The bad news is that this warning doesn’t seem to be mentioned on the game box of Halo: Reach, which could potentially result in many red-faced new Halo: Reach owners. Have you noticed any issues with your Halo: Reach gaming session yet?
