Depths of Doom Trilogy

The Depths of Doom Trilogy was a commercially-sold compilation released by GT Interactive 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 via the id STUFF application

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

The collection is particularly notable for its over-sized, high quality packaging with embossed detailing.
