Desolated - The Crying Fate is a Total Conversion based on Doom 3. It comes with a complete new storyline about the shade between good and evil plus two other gamemodes. A quest-, rpg- and moneysystem are just a few of the many new game mechanics that will await you. If you want to see everything you'll need at least 7-8 hours... but let the game speak for itself, download and have fun playing!
This patch is important for every Doom 3 owner having Patch 1.3.1 installed. First install the demofile itself and the patch afterwards.
