Comparison of versions
Numerous changes exist in the level as compared to its PC version:

Geometry simplification

 * Several rooms, including the central chamber and the south-western room, have had their heights reduced.
 * The number of walls in the central chamber is reduced, giving it a more geometric shape. The wooden ledges in this chamber have also been made square.
 * The staircases in front of you at the start of the level have been made square and reduced to two steps.
 * The small pillars either side of the switch requiring the yellow skull key have been removed.
 * The brightly-lit sectors on the ledge west of the cyberdemon alcove have been removed.
 * The overhanging ceiling above the door leading to the exit switch has a straight edge instead of a zig-zag.
 * Most staircases have fewer steps.

Other

 * The cyberdemon and all the barons of Hell are replaced with Hell knights.
 * After teleporting into the cyberdemon alcove, you must press a switch to lower the wall and open secret #3. In the PC version of this level, you press use on the wall instead.
