Halo: Reach has taken over the gaming world with its release this week, but it seems that not all Xbox owners can hop online and experience the game’s co-op just yet. For those gamers who own the newly released Xbox 360 S Arcade model with the 4 GB hard drive and try to play Halo:Reach co-op, this is what you will see, “One or more players do not have the hard drive required for this game type”. If you have been affected by this issue don’t worry. It will more than likely be fixed before the week is over. Play the competitive multiplayer until then.
