Ascend the mountain to find out what the UAC were getting up to and stop the hellish invasion!   V1.2 (Newer than IDGAMES, contains more visual fixes and one softlock on MAP28) CPD V1.3.zip   Ever since the UAC set up shop in the mountain you've been getting complaints from the nearby towns. They range from excessive nukage seeping into their water supply to unstable nightmares assualting their sleep.   Despite this, the facilities within the mountain kept growing, until one day the whole facility went dark, no contact with the outside world.   As the only soldier close enough to make a difference you hopped into your hover vehicle to investigate, travelling through the mountain ranges until you arrived at one of the many entrances into the maze of facilities.   Before entering you set up your recon drone to go through the many access tunnels in hopes of finding out more whilst you will burst through the main entrance. Your goal is the summit and whatever they found up there...   Map Format: DOOM2 IWAD: DOOM2 Maps: MAP01 - MAP32 Gameplay: Single player and CO-OP. Difficulty Settings: Monster counts adjusted for easy, medium and hard. Tested in: PRBoom+, Gzdoom, and Crispy Doom (Some issues with skies and slime trails in Crispy Doom but works fine)   Screenshots below:       More screenshots!
