Congestion 1024 is a 2005 megawad for Doom II. All maps are designed so that the playing area fits entirely within a 1024×1024-sized area. Authors were allowed to define sectors outside of this area for the purposes of gameplay, detail and scenery, as long as they are not reachable. MAP01 and MAP19, however, include accessible areas outside of the 1024×1024 boundary. This project was influenced by the Exquisite Corpse community WAD. A spiritual successor, Claustrophobia 1024, was released in 2009.
