As always, Rugger and Duc... who know all things... helped get the redirect going. So uploaded all the CBP1 maps and they are in the Mutant rotation. Need to fiddle with that since they are all the last ones. When finished downloading, they wont go in your game install maps folder but a separate cache location since they are compressed archives. If you want the actual maps in their proper folders you can install the packages yourself or I am pretty sure there are tools around that will uncompress whats its the cache and do it for you.
Rules are short: The Mutant Deathmatch variation is where the first person to kill becomes the Mutant; a player with a starting 199 health and 150 shield, increased running speed, higher jumps, and 999 ammo for every standard weapon. After this, every player (with one exception) can only try and kill the Mutant, but in turn the Mutant can kill every other player. The person who lands the killing shot will then become the Mutant. The exception is the Bottom Feeder, the person with the lowest score. They can also kill other players. And, like a normal Deathmatch, the first person to reach the required amount of points (20 ATM) or has the highest score when time runs out wins. 16 players... which could mean 4 players and 12 bots.
If any UT players remember great DM maps let me know what they are and I will add them. One last thing. I havent install it yet but the old anti-cheat package should still work from what I read. Up until they stopped supporting it way back when. So must still watch for any cheaters and deal with them.
