The insane_doom3_map_demo.zip file you have requested: Maps / First Maps / Insane DOOM 3 (Demo) - 16.26kb is not available. Perhaps try browsing all files for the game Doom III and upload any files you want to share or are missing. This is the only information we could locate:
This is the map version of [file=\"40282\"]my mod project[/file] soon in Insanedoom3 v1.2. There will be more of the map in it as well as the upgraded monsters so there will be a humongous challenge in 1.2. To load the map type in console "map insanedoom3" that's it oh and for installation dump the pk4 in the base folder.
