Altitude

Altitude is a single-level PWAD for Doom II, created by Thomas Seifert (tourniquet) and released in December 2016. It uses the music track "E1M1SAS" by Zan-zan-zawa-veia. Additionally, it includes the music track "Brundle" for the title and intermission screens, also by Zan-zan-zawa-veia. Altitude is a vanilla-compatible map that is built exclusively using textures from Doom and Doom II, and combines a realistic cityscape with abstract, dreamlike visuals in a highly non-linear map. It was released on the same month as another large single-map release by tourniquet, Miasma.
