Doing the 'Challenge Lobbies' on World At War requires the same steps as the others. There is no need to re-format either console, as that won't do anything. If you re-format it, it won't ask you to update to the newest firmware. It will just keep it on the one you currently have before doing the format. I rented World At War for five days, so I could **** off, and mod it. It's not that cool, as Treyarch made it. :megusta: But that's my opinion. :y:

Just stick to what you have already, no need to change.
