As promised, here's my rendition of e3m1.
http://www.sendspace.com/file/k788hi -accidentally uploaded only the resource pk3

, here's both the map wad and resource pk3.
Features
-converted to take advantage of UDMF features
-complete retexturing using modified AVP2 textures
-new inventory items -flashlight and flares (you start with the flashlight. default key "F")
-rearranged enemy and item placement (you don't get all weapons at the start and ammo is more of a precious commodity)[/color]
PROTIP: Save your grenade and flame rounds for the end
-some minor cosmetic changes to weapons (gunflashes and grenade smoke)
-music from Alien Trilogy (if you don't like it there's always "stopmus" in console)
Some things you should be aware of
-
This map has a VERY big surprise at the end. (which can be completely spoiled if you view the PK3 contents, so please finish the map before you go snooping around in the data)
-This map is meant to be played with either DOOM or DARK sector light modes. Any other mode robs it of its atmosphere.
-Because of the heavy reliance on dynamic lights, this wad is meant to be used in GZdoom.
-the playerclass had to be changed to accommodate the weapon changes and inclusion of the flashlight.
-the map has 4 secret areas, but for some reason the UDMF format does not make this apparent.
-the next major update will follow Ben2k9's update to the main wad, but if any problems show up beforehand, I'll release a quickfix ASAP.
