So I'm about to renew my Gold subscription [we didn't have fast enough internet in my student apartment until last month] and I am going to want to buy the new map packs for Halo 3, and I'm doing that online today, can somebody tell me what content I don't have on my ODST multiplayer disc? I know it comes with some of the extra content but will I still have to buy more? For example, the Mythic II pack came out last month, so I assume I'll have to buy that one.
Please and Thanks for all the help ahead of time.
