Depths of Doom Trilogy

The Depths of Doom Trilogy was a commercially-sold compilation released in the fall of 1997. It included three CD-ROMs:


 * 1) Ultimate Doom version 1.9 (DOS and Windows 95); Heretic version 1.2 shareware
 * 2) Doom II version 1.9 (DOS and Windows 95)
 * 3) Master Levels for Doom II; Maximum Doom; DWANGO version 2.02; locked versions of Ultimate Doom, Doom II, and Heretic. The CD also contained several thousand user-created levels, some of which contained content taken from copyright materials (such as sounds and sprites from television shows such as Monty Python's Flying Circus and The Simpsons).

The package also includes a single instruction manual containing information edited together from the three individual Doom game instruction manuals.
