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. 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.
