MAP24: Quarry (TNT: Evilution)

MAP24: Quarry is the twenty-fourth map of TNT: Evilution. It was designed by Dean Johnson and uses the music track "Between Levels" from Doom II.

Secrets

 * 1) At the south-west part of the open area with two towers, there is a corridor shaped as a horseshoe. Go to the most southern part of the corridor and shoot a northern wall. The wall will open a room with some goodies and a lift in the northern wall.
 * 2) East from the level exit, there is a corridor leading to a teleporter, which takes you to the eastern tower (the one with the blue keycard). Halfway of the corridor there is a fake wall containing a shielding suit.

Routes and tricks
This map is easy to complete under UV speed and NM speed rules in under 20 seconds with the proper route. Upon starting the level, head to the cavernous room in the north, exit through the south, and enter the lava cavern in the southeast. Enter the teleporter that is lowered, and grab the blue keycard when the platform rises. Head down to the southern platform, open the blue key door, and flip the exit switch. The fastest demos using this route are Vincent Catalaá's 00:18 UV speed demo and his 00:19 NM speed demo.

A highly unusual trick, however, allows the level to be finished in even less time. The sector representing the teleporter in the southeast cavern is marked as a special damaging floor that hurts you even in God mode and ends the level when your health drops below 11%. Such sectors are used in Doom's E1M8: Phobos Anomaly and The Plutonia Experiment's MAP11: Hunted (in the "wrong" exit.) Normally, though, this would not occur since you would be teleported as soon as you step onto it. However, if you manage to skip over the teleport linedef, and your health is low enough, you can beat the level in under 20 seconds without even reaching the exit room. This trick was discovered by John Keniry, and was subsequently used in the current record-holding UV and NM speed runs.
