MAP15: Tricyclic Looper (BTSX-E1)

MAP15: Tricyclic Looper is the fifteenth level of the first episode of Back to Saturn X. It was designed by Brett Harrell (Mechadon) and uses the music track "Quicksilver" by James Paddock. The par time is 5:45.

This level contains a secret exit leading to MAP31: The Hard Way in the beta release, and MAP31: Optical Hopscotch in the first non-beta release.

Secrets

 * 1) On the way to the yellow key, on the northern open air corridors full of barrels where you get ambushed by cacodemons, a grated wall is flanked by two green lights. Lower it for a green armor. (sector 1036)
 * 2) In the computer room near the center of the map, on the west side of the computers, push the only one with a green screen to lower it, leading inside of the mainframe (sector 237). While several items such as a light amplification visor can be found in this secret, its primary purpose is a switch in the pillar with the blue key that unblocks access to the key itself later on.
 * 3) After the yellow door just south of the map start, there is a room with a super shotgun, which will reveal a cacodemon when taken. In this same room, press the green computer texture with the flashing light. The adjacent wall lowers, revealing a corridor with a soulsphere (sector 795). This secret must be opened to open the way to the secret exit.
 * 4) At the very southwest area, there is a room with computers and a floor with wiring where the walls lower revealing pinkies and Hell knights. In the north of this room, near the northern door, there is a wiring panel with green lights. Activate this to lower some nearby pillars, giving access to a plasma rifle. (sector 876)
 * 5) South of the red keycard and just north of secret #4, there is a narrow corridor, guarded by zombies on platforms, with a lift at the end. Lower the lift, and as it rises, jump on to the west platform and take the rocket launcher. (sector 653)
 * 6) At the far southeast end of the map, head up the stairs and use the lift up. From there, go down the hall to the right to the dead end with boxes of bullets and shells. Notice that one of the lights here is purple; use it to lower the floor down to a walkway with boxes of rockets and energy cells. You can drop down to the BFG9000 from here. (sector 391)
 * 7) At the room with the fans and the switch that raises the steps to the blue key. One of the fans here is broken. Drop down here and look right at the two metal beams for a glowing switch. Use it and then a megaarmor will be revealed behind you. (sector 612)
 * 8) This is the sector where the blue key is located. (sector 533)
 * 9) Go up the stairs and through the red key door, and after the next door, on your left, use the darker patch of wall to reach a dropoff where you can get a soul sphere and energy cell packs. (sector 110)

Bugs
A shotgun guy (Thing 690), two rockets (582 and 584) and four sets of 4 shotgun shells (585 through 588) have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
