I need help. I don't have the campaign maps on my hard drive since I don't use them, so the campaign mode on the main menu is pretty useless. And I know it's fully possible to not have the option there, so I was wondering if someone can help me out and tell me how to get rid of it because i am absolutly clueless.

Are you trying to just get rif of the campain maps?

No. He's not trying to get rid of the maps -- he already did that. He wants to get rid of the 'Campaign' option in Halo's main menu since he doesn't play the campaign anyway. Just an aesthetic touch. As for how to do that, I think there's no easy way besides some good old-fashioned hex editing.
