Who ever wants the mod heres the link, Note that im not registered at rapidshare so only 10 downloads until i make an account
also right now i only have the mac version but you can take the mod out of the folder and put it in the windows version.
NOTE: There is a glitch right now where if you die in MultiPlayer, it will crash.
EDIT: OH MY GOSH I AM STUPID!!! I forgot to say the credits!: Thanks to the Creator of H3_Sandtrap (Halo Custom Edition Map) for the Guns, HUD, New MC Model, Vehicles, and sounds. The Creator of the Halo 3 ODST Mod for the Menu Hack, and Music, Thanks to Me for compiling all of these mods into one.
