Point of No Return - The Doom Wiki at

Point of No Return is a single-level PWAD for Doom II, created by Michael Philleo (Job) for the ZDoom source port. It is a large techbase map, and represents an early attempt at emulating the style of Playstation Doom through the use of sounds from that version of the game but also the colored sector features from the ZDoom engine used to simulate similar environments. It uses a music track entitled "downlord" by Ubik (aka RocketMermaid).
