Is there any way to play Battlefield 3 multiplayer from more than one xbox 360 it's installed on?
There are 2 possible options for you, I think:
- Take your profile and game data on a USB drive with you.
- Recover your profile on the other 360, and re-download the Online Pass. This should be available to you on the other machine since it was previously downloaded. The full steps to re-download content are here, but basically: Guide, Settings, Account Management, Download History, find the item and re-download it.
This all being said, I dont' have the game and haven't tried it, but let me know if it works.
If you recover your gamertag and re-download the online pass via Account Management > Download History, you can play online again.
Of course you can, just download your gamertag to the system and re-download the pass. Instead of entering the code again, just click re-download.
