Primary Excavation: Artifact Dig is the twenty-seventh and final level of Doom 3. The player must defeat the fourth and final boss, the Cyberdemon, in order to seal the Hell portal. Imps, Maggots, and the Cyberdemon are the only enemies in this level. An exploratory player may find the hidden "id Software" PDA, containing messages from several id Software employees.


Spoiler Warning: Plot details follow.

The marine descends to the Primary Excavation Site where he finds an enormous cache of supplies waiting for him. After taking as much as he can, the marine heads into the Hero's Burial Chamber. A wall opens up to reveal a passageway leading to a stone chamber that takes the marine down into another secret passageway aligned with candles and demonic icons. Coming to the end of this passageway, the marine enters an enormous cavern. Here is the Hell Hole and as well as the game's final boss: the cyberdemon.

The marine battles the cyberdemon and its imp and maggot minions which come pouring out of the Hell Hole. Despite the odds, the marine defeats the massive demon after striking it four times with the Soul Cube. The Cube kills the cyberdemon by slicing off one of its legs, then impaling its blades into its head. The Soul Cube then flies into the Hell Hole, causing lava to boil over and solidify, sealing the portal and ending the demon invasion at last.

Days later, the Fleet from Earth arrives. Marines and sentry bots enter the Delta Complex to find the entire base in ruins with everyone dead. They manage to locate a single survivor - the marine - who is promptly evacuated off the planet. Counselor Swann is also found, but he has died from his wounds. Dr. Betruger is nowhere to be found...

The final scene of the game reveals that Betruger is in Hell and has been transformed into a giant dragon-like demon: The Maledict. The Maledict swoops down at the screen which cuts to black, and the credits roll.

Spoilers end here.
