The World of Deth: From Heaven To Hell

The World of Deth: From Heaven To Hell is a Doom II megawad of 32 maps developed by Morten Strømsvold (The Big One). Development for the megawad started in 1996, and the final wad was released on 3 May 1997, with a bugfixing update following on 19 November 2000. The wad was originally in development for Ultimate Doom before switching over to Doom II after many of the maps had been completed, as the author switched from the DEU to DETH level editors.
