Virgil the Doom Poet designed various levels for Doom and Doom II but became inactive after 2004. With the release of ZDoom 2.2.0 and the latest version of GZDoom (which supports all of 2.2.0's features), Virgil intends to release new levels. Possible upcoming work includes Space Fragments, Claustrophobia 2 and the long-abandoned Lake Avalon's Fall.
