Whispers of Satan

Whispers of Satan is a Doom II megawad that requires a Boom-compatible source port created by Paul Corfiatis and Kristian Aro which was released on September 15, 2009. In a personal meeting in August 2005, Kristian decided once Death Tormention 3 was complete that he and Paul were to make a complete 32 level megawad for Doom II, plus a few ZDoom specific secret levels and work began on the project in October 2006 with Paul completing the project's first level, MAP12: Blood Station. The story is set in the distant future but similar to the original Doom II, with the player starting on Earth and progressing into the depths of hell. Whispers of Satan also contains original music composed by both Paul and Kristian. With the modern source ports of today, the levels themselves in Whispers of Satan have superior detail compared to the original Doom II.

Both authors have stated that Whispers of Satan would likely be their final contribution to the Doom community, though both have released more material since.
