After 2-3 months of work I've finally got what I think is an ok mod for the Halo 1 demo/ trial. I would like to have some other people download the mod and try it out (don't worry, instructions are included), you will need to download the halo demo though. If you would like to give it a try feel free to download it from here ~> http://www.megaupload.com/?d=QBMMB8C6
Thanks :)
