This GZDoom mod totally converts Doom, Doom II, and Final Doom into a full-fledged Aliens game. You must face Weyland-Yutani androids, predators, and xenomorphs a celestial battle for survival.
UPDATE: [1.1] -I've reduced the speed of the Xenomorphs, as many were complaining that they were too fast. -I fixed a few other glitches, and errors as well. // I have combined Aliens:The Ultimate Doom with Alien Trilogy graphics. Moreover, using the original Alien Trilogy graphics, I have created new rotation attack frames, blood and gore sprites. This mod takes the aesthetics of Alien Trilogy, and combines it with the action and game play of Aliens the Ultimate Doom. Special thanks to Lex Safanov for decompressing the Alien Trilogy files!
This mod converts doom into Alien Trilogy, combined with the gameplay, gore, weapons, radar, spawning system, and other aspects of Aliens: The Ultimate Doom.
