MAP45: Tenements (PlayStation Doom)

MAP45: Tenements is the forty-fifth level of the PlayStation and Sega Saturn versions of Doom, and the fifteenth level of the Doom II episode. It is based on the original MAP17: Tenements, with modifications made to adapt the map to the consoles' limitations. The author of the original map is John Romero.

Secrets

 * 1) (sector 78)
 * 2) (sector 112)

Bugs

 * Trapped in walls inside the fenced chamber to the west of the starting area, two imps (things 14 and 15) cannot be killed on UV difficulty resulting in inability to reach 100% kills toward the level's end.
 * In the blood room to the west of the starting area's junction where the red skull key is found, eight textures (linedefs 221-224, 226, 227, 229 and 230) on the white rock bridge have improper offsets appearing distorted and inverted.
 * In the north-western room with the translucent cacodemon cage (formerly an arch-vile cage in the original PC-version), some walls (namely linedefs 859, 860, 861, 862 and 876) appear slightly stretched due to a large height of the whole room.
 * Because the aforementioned translucency of any visible thing in the game is consistent for spectres only, the applied blend mask effect performed on the cacodemon in the cage (thing 435) was by a strong likelyhood not meant to be done deliberately, and therefore considered a bug.

Comparison of versions
Several changes were made to this level compared to the PC version.

Geometry simplification

 * Most staircases have fewer steps, like other levels in PSX Doom.
 * The octagonal step around the blue keycard has been removed, and the square step is slightly larger.
 * There are four yellow skull pillars opposite the yellow door instead of five.
 * The archways over the corridor past the yellow skull pillars have flat ceilings rather than being stepped.

Room design

 * The "entrance door" at the start of the level is removed.
 * The narrow path leading to the red keycard has been made wider.
 * Walking up the south staircase in the western room (with the yellow keycard) causes a door to open behind you and reveal a soulsphere. In the PC version of this level, walking through this door causes a switch to rise from the floor at the top of the staircase; in the console version, a door in the north wall at the top of the staircase opens instead to reveal the switch.

Monster placement

 * Pain elementals and Hell knights are replaced with cacodemons.
 * Arachnotrons are replaced with chaingunners - two each on Hurt Me Plenty and Ultra-Violence skill levels, and one each on I am a wimp skill level (even though the arachnotrons do not appear on the easiest difficulties).
 * The caged revenant in the northern-most area is replaced with a cacodemon, while the revenant guarding the blue keycard is replaced with four imps.
 * The caged arch-vile in the north-western room is replaced with a cacodemon, which is translucent due to a mapping error (see Bugs).
