This is Halo derelict, a map that I had wanted to do for UT and found that it had already been done for UT 2K4 by a team called Torlan...http://torlan.forerunners.org. Out of curiosity, I tried to copy and paste their UT2K4 Halo Derelict map into the UT99 editor. Wasn't happening! I eventually got the textures imported into UT99 and a few sections of the map. Most of the brushes were reworked to get better geometric symmetry, combined together to optomize geometry,and moved around or tweaked a bit to eliminate a multitude of rendering glitches. Working with the UT99 editor is pure hell as any mapper can attest. It has a self-destructing personality type. Anyways, props to Torlan, the creators of Halo; MS, Bungie and Gearbox, etc.,Dwight Jack for a tracker tune called "2 Souls at Once" http://web.lacasadialice.it/dwjack/index.html, [^..^]Nick for suggesting secrets be added in the map, and MOST IMPORTANTLY, Vlad's Army, the world's greatest sniper clan, homepage: www.vladsarmy.tk. Without them, I would have never learned how to map, skin, do websites, or enjoyed playing the greatest first person game ever created for so many years. 
ENJOY!
