The Lost Levels


Not to be confused with Lost episode (disambiguation), The Lost Mission, or the PSX Doom: The Lost Levels (add-on to the PlayStation Doom TC).

The Lost Levels is a new episode for Doom 64 added in the 2020 re-release. All maps in the episode were authored by Nightdive Studios employee and Doom community member Samuel Villarreal (Kaiser).


Taking place an indeterminate amount of time after the Doom marine slayed the Mother Demon in the original campaign, the beginning of the episode finds the marine stranded outside of Hell with none of his weaponry on a distant vacated UAC base. This occurred through the powers of the Mother Demon's sister, known as the Sister Resurrector, who hoped to stop his campaign against Hell by sending him away.

The marine must fight his way back into Hell, recover the Unmaker and the three Demon Keys, and then take his revenge in order to continue his quest against Hell.

Spoiler Warning: Plot details follow.

The episode's ending makes reference to the Slayer Testaments of Doom (2016), implying that the journey of the Doom Slayer has begun:

"A grim vision takes hold of your mind as the demon carcasses steam in your wake. Stretched before you is a path of perpetual torment... A path through DOOM..."
