Unsung is a Wolfenstein 3D mod by Nembo that was released on April 25, 2011. It is set in the trenches of the Western Front during World War I. It features the players as an Allied Trench Raider attempting to take out a German Artillery Bunker, avoiding machine gun nests, chemical clouds, and flamethrowers. It received the Wolfenstein 3D Dome Monthly Award for April 2011. It was also ported to the Sega Dreamcast console.
- There is an unused map in the files, set atop a U-Boat in the middle of the ocean. This was intended to be another Instant Action map, however it was scrapped when Nembo felt it did not look right. Some of the textures from this map were repurposed and used during the story.
