PSX Doom: The Lost Levels

Not to be confused with The Lost Mission (an add-on for Doom 3), The Lost Levels, or Lost episode (disambiguation). PSX Doom: The Lost Levels is an add-on to the PlayStation Doom TC aimed at providing a conversion of the Doom levels that weren't originally included in the ports of Doom and Final Doom to the Sony PlayStation. The maps reuse the original soundtrack for PSX Doom and Final Doom, though an optional music pack features new ambient music created by DeXiaZ.
