The First 15 Minutes of Final Doom (PlayStation)

Copied from DoomWiki.org:

Final Doom for the Sony PlayStation was created by the same team at Williams Entertainment that produced the PlayStation version of Doom, reusing the same engine. It was released on October 1, 1996, including a mixture of 30 levels from the Master Levels for Doom II and the Final Doom missions TNT: Evilution and The Plutonia Experiment. The instruction booklet erroneously states that the game contains 30+ levels rather than 30 exactly. Although the box does not mention the Master Levels, the back cover of the instruction manual acknowledges their inclusion.
