MAP22: The Catacombs (Doom II)

MAP22: The Catacombs is the twenty-second map of Doom II. It was designed by American McGee and uses the music track "The Dave D. Taylor Blues". The par time is 2:30.

Essentials
Right off the bat, secrets #1 and #2 are accessible if you wish to go that route. If not, simply lower the lift in front of you and ride it up to the central area. Kill the chaingunners on the "compass" platform and drop into the nukage pit, killing any spectres that get in your way. Lower the green lion-faced block in the northwest corner of the pit and ride it up. In this next area, flip the switch in the corner and pick up the berserk pack. Continue up the stairs and along the path, killing monsters along the way. When you reach the upside-down-"T"-shaped structure, go through the door on the south side, kill the imp, and go through the teleporter.

From here, pick up the blue skull key and run along the walkway back onto the compass platform. Walk along the bridge to the west and pick up the rocket launcher. Drop back into the slime and lower the baron-faced block in the northeast corner. Drop down the shaft, kill the demons, and raise the bars using the blue key. Walk through the arched tunnel and drop into the next area. Flip the switch to lower a wall, releasing a baron of Hell. Kill it, and flip the switch to lower the lift to the red skull key. Pick it up (secret #3 is here) and follow the passage back out to the bars. Go around the arched tunnel this time and flip the switch at the end. Be wary of the chaingunners that are released upon doing this. Quickly make your way back through the now-open bars before they close again. Lower the green pillar in the corner to get back to the central area. Drop into the slime one last time, and lower the gargoyle-faced block in the southeast corner. Open the red door, killing more chaingunners along the way. Flip the switch behind the last door to exit the level.

Secrets

 * 1) In the northwest corner of the starting room, there is a slightly recessed dark green wall. Open it to reveal a secret room with armor and a box of rockets. On Hurt Me Plenty skill level and higher, the room also contains a spectre and a supercharge. (sector 85)
 * 2) On the southern wall of the starting room, there are five torches. Press the use key on the green torch to lower a floor to your right (sector 125) that leads to a plasma gun and a teleporter to the main area.
 * 3) Immediately after picking up the red key, open the wall with the carved face of a baron of Hell to your right. (sector 14) Behind it is a teleporter to secret #2.

Bugs
The four chaingunners immediately behind the red key door are blind. They will not see the player character if he opens the door, unless he hurts them or goes past the doorway. This is due to a bug in id Software's REJECT map builder which fails to account for certain door constructs.

The switch (Linedef 120) that raises the platform (Sector 90) to the rocket launcher is repeatable. Using it twice will raise the platform again and reveal a small Hall of mirrors effect on sidedef 56.

Design Oddities
All five deathmatch starts (Things 76, 77, 78, 79 and 82) have no flags set for any of the three difficulty classes, but because of special handling in the engine, they function normally in the level.
