Master Levels for Doom II

Master Levels for Doom II was released on December 26, 1995 by id Software as an official expansion pack for Doom II: Hell on Earth. It was also included as a bonus on the Doom 3: Resurrection of Evil Xbox game disc in 2005 (which included significant differences from the original PC version). The PlayStation version of Final Doom includes 13 levels from Master Levels for Doom II. On November 20, 2012, Master Levels for Doom II was released for the PlayStation 3 as part of the Doom Classic Complete PSN package, along with The Ultimate Doom, Doom II, No Rest for the Living, and Final Doom for a total of 162 levels.

The CD contains 20 WAD files created by various authors under contract. The file TEETH.WAD contains a secret level, so there are a total of 21 levels.

As a bonus, 1,830 amateur custom PWAD files downloaded from the Internet (collectively called Maximum Doom) and a Master Levels for Doom II poster are included. Version 5.9c of the Doom-It tool, created by Chris Badger, is included as well. Also of note is that some of the contracted designers for the Master Levels had levels they had previously released on the Internet that were included in Maximum Doom.

Master Levels for Doom II is available on Steam, either as part of the Id Super Pack or separately. However, Maximum Doom is not.

In the PSN release, the Master Levels are ordered in a sequence to form a 21-level episode.

Master Levels Menu Interface
The is a 2010 ZDoom WAD created by Zippy which is designed to replicate the menu functionality of Doom-It in-game and allow all 21 of the levels to be played without needing to restart the engine each time. After the WADs are added, the Menu Interface can be loaded in ZDoom and used to play each WAD at any skill level in whichever order the user wants; they will be returned to the menu each time they complete a level.
