Hadephobia

Hadephobia is a 2013 megawad for Boom-compatible source ports. It was started in 2010 by Chris Bourke (purist) under the name "Progressive Fiction," in which the levels would follow a continuous storyline written by the designers, and each of them would begin where the previous map left off. The map set was a runner-up at the 20th Annual Cacowards.
