Not sure if anyone else checked out the Akimbo Arena Mutator for UT2004, but it was a hell of a lot of fun. Those dual shock rifles were a blast, pun intended of course.
I tried looking for the original source but couldn't seem to find it. The author mentioned about extracting the source from the .u file, but considering my noobishness with UT mods/muts, I have no clue about doing such a thing, and googling offered no help on the issue.
So... if anyone has free time, the willingness and/or want to do such a mutator.. err I'd appreciate it. And I'll give you a cookie or something. Maybe some beef jerky.. who knows. Gotta check what's on sale :P
