While I'm not involved in anything concerning Halo CE, I'm trying to make a better Halo 2 campaign with one shot battle rifles, so maybe we could exchange ideas. Just a thought.
I play on XLink Kai as FJGamer. (FJ is my Halo 2 profile.) I have a mic, and I love to play 8 on 8 mics versus no mics. I also love to mod Halo 2. For some reason Halo 1 won't work on system link, though.
