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.

Secrets

 * 1) In the southwest room, go to the southwest corner and climb up the bricks to get a soul sphere. (sector 153)
 * 2) In the southernmost area, head to the southeast corner and lower a pole there. Shoot through the north wall, then head west and south into an alcove with a health bonus. The wall opens up revealing an armor bonus, and then a computer area map appears afterward. (sector 171)
 * 3) Head east from the rocket launcher and when the floor lowers to spectres, go to the northeast wall and use it. This opens another wall in the northwest corner, but this will close if you leave the northeast corner. While still in the corner, shoot the northwest wall to open a megasphere in the northeast corner. (sector 507)

Demo files
