Team Orbit released a total conversion for ut99 back around 2001 or close to. Much more Egyptian themed, an entirely new set of weapons (boomerang gun ruled) new skins for the default ut99 model types, and the mechs. It had everything and various gametypes.
I got rid of the bulk of it but I kept the mechs. I don't know of anywhere it can still be downloaded.
Put on bots, the mechs are beyond lethal. Especially as I tripped out their skills to scary levels. They're fun to play to but using actual ut99 weapons is nearly impossible, you're stuck with whatever weapons that particular mech has built in.
Team Orbit made a followup one, with more advanced mechs, but they did something to the AI that made them less lethal until someone attacked them. Otherwise they just kind watched you creepily. They also added vehicles, around 2003 I think, and battlesuits players could get inside and use.
Their current site is here:

They're still working on projects for the various Unreal/UT games.

You can grab Neo Cairo from there.
