Nightomb

Nightomb is a single-level PWAD for Doom II meant for limit removing source ports and released in December 2008. It was designed by Alexander S. (Eternal) and for the music track it uses a heavily modified version of "Dungeon" from , originally composed by Eric Heberling and modified by BPRD.

This map is the second PWAD in Eternal's 2x2 series, preceded by Eclipse and followed by To Fight. Just like its predecessor, it features two textures and two flats used throughout the entire map, but features only custom sounds and no changed sprites or DeHackEd work otherwise.
