@Spooky: If you know some one with Halo 2 I can hook it up for GTA. there really isn't much of a difference from 2-3 on the Hog.
Just textures really, and making the cage/seats for the transport on the back.
I'll see if I can't dig it up. But if you find it PM me and I'll see about getting to work on it.
Edit: I'd also like to note that a while back I converted the Hog from H1 to Carmageddon 2, it's a straight port so you know
my work will be high quality.
