u can become a vampire again on xobx 360 oblivion...How?... go to caves, some of them have vampires... that's my best bet, other wise join the dark brother hood and do all their quests and the leader (who is a vampire) will give you a choice if you want to become a vampire or not. if you choose to do so he will give you phehporic hemophillia (idk how its spelled xD) and after a few days ur a vampire. :)
You cannot turn into a werewolf in Oblivion, though you can turn into a vampire by being bitten by vampires, though there are another source of becoming a vampire, you find it out, I am not going to tell it...
What exactly is your question? Yes, Oblivion has an Xbox 360 version, if that was what you meant.
You can't become one on xbox360.
You can play it while signed into xbox live, but you cant play with other people through xbox live on oblivion.
Oblivion can either be for the XBOX 360, or for your computer.
