Playing on my friends Xbox 360, both of us have gold accounts, my profile, DLC, and save data are on my USB stick and I was setup on control pad 2. I found last night I can share my pre order bonus DLC Recon helmet, in Halo Reach with my friend. No shady methods, he simply went into the armoury and it was there for him to use. I don't know if this is a bug or a glitch or simply by design. He was also able to play on all of my DLC maps aswell though when we both tried to go online with other people we had difficulty sometimes getting the DLC maps to load. He has never played Halo: Reach on his account, until last night when I went to his house with it.
Now I thought we weren't supposed to be able to access the content of other users? Is this intentional for this game? Or a loophole?
