Aliens TC for Doom - Levels 1 + 2: Landing Pads + Atmospheric Processor
To celebrate it's 20th anniversary, I playthrough Aliens TC for Doom 1, widely considered to be the first Doom mod ever released.
Aliens TC has gone through several iterations, updates and re-imaginings, but I'm playing through one of the (if not THE) original release, which I found here: http://www.doomwadstation.net/main/aliens.html
Although not necessary to run the mod, I'm running Aliens TC with the GZDoom sourceport, which can be found here: http://www.osnanet.de/c.oelckers/gzdoom/index.html
And, of course, you'll need a copy of Doom 1 to play Aliens TC. Doom 1 can be found on Steam:
