Claustrophobia 1024 is a 2009 megawad, and the spiritual successor to Congestion 1024. Similarly to its predecessor, all of its levels are designed such that gameplay is restricted to an area of 1024×1024 map units. The project was led by Brett Harrell, began on July 10, 2008, and was released on June 17, 2009. Although a significant portion of the soundtrack is derived from other sources, it includes original compositions by Eric Baker (The Green Herring), Paul Corfiatis, James Paddock (Jimmy), and Stuart Rynn (Forty-Two).
