Doom (1993) Doom:the Tei-Tenga Incident v.Shareware Edition 401u46

Description
It has been a long time since the doom bible was wrote by tom hall in 1992, before leaving id software due to differences over dooms direction. In 2000 the doom bible was released on doomworld.com to coincide with the fifth anniversary of doom. After the point several mods for several source ports, and even quake have attempted to create a mod or game based on the doom bible. None have completed an entire episode that is playable from start to finish. Until today.
The aim of Doom:the Tei-Tenga Incident, is to finish the doom bibles story, creating a fun, interesting, and atmospheric game in the processes. What makes this doom bible mod different from the rest is the fact that it is being constantly worked on, and not put on indefinite hiatus, or cancelled outright. Or suddenly dissapearing off the face of the earth.
Use GZDoom to launch the mod.
