This is a singleplayer map I created using Doom3. It's a tough map with four hidden powerup areas. (armor, Shotgun, chainsaw and the classic BFG). I hope you enjoy the hybrid gameplay of Doom3 with Doom2 elements.
Install Instrutions for my DOOM3 map.
1. Download existential.zip and move it to doom3/base.
a. Change the extension from .zip to .pk4
2. Play the game.
a. Type in the console "map dc/existential" - press enter and my level should load now without any problems, give it a second to load.
b. If you're not running full screen just press "Alt+enter" like you would in windows media player to go full screen.
