Now that I'm back home, I can finally post this on the news where it belongs.

Louis Wu of halo.bungie.org points out an interesting post on their forum:

After a good initial reaction from the public and a e-mail from Doug Zartman saying Halo ships with everything needed to make a mod I've decided to start the Battletech mod for Halo.

If you are interested in helping us please e-mail me at chris@wrong.button.com We need coders, modellers, texture artists and level designers. Our webpage is will be constructed shortly and we'll plan for awhile until Halo is released.

Everything needed to make a mod, eh? Nice.

Update: The post's author, Jex, has just corrected himself; the mod will be for Macross, not Batletech.
