Hi, I am the White Mamba Overlord of our group the ODSM.
We are not a clan, and we don't play the game for competition. Instead we play for fun, and to hang out with friends. If you are interested in joining go to our group homepage and sign up. Membership is open.
We are mostly a Halo 3: ODST group for help with achievements and stuff, but we also will play a lot of Halo 3 matchmaking.
Yes, but only for in vehicles. I loved sitting in the side seat of the warthog in Halo CE. It was awesome, and I would love to drive and gun the same way! =)
But for just walking around I don't think it should. It could possibly make for an unfair advantage. IE: Being able to see someone sneeking up behind you, and being able to look around corners without actually looking around the corner.
