MAP26: Proving Grounds (Strife)



The Proving Grounds are some sort of Order training area.

This is a very complicated and confusing level; I had to work out the most efficient path through it by using backward chaining (what some puzzle-solvers and other logicians sometimes call "synthetic reasoning", although the Wikipedia article of that name claims that to be a metaphysical term rather than a logical one).

Mission G11 / B9: Onward to the Lab
As Blackbird has just told you, go down either lift to a courtyard; turn left and go to the lift in the southwest corner (A). Walking off the top opens some bars, go through those and the door behind. Beware of the heavy nasties in this room. Turn right, and go down the lift to a switch (B); operating this removes the obstacle from the nearby stairs. Back up and out through the door you didn't enter by; down either staircase, and at the bottom turn west (left). Down a lift, around and down another lift, and turn right (south), around the building, and through the door (C). Ride the elevator up to a room full of goodies, and exit through either door; go around and through a slide door to a small room with a switch (D). Pressing this opens a teleport elsewhere.

Exit, down the lift in front of you, and retrace your steps to (A); down the lift and across the yard to the other lift in the northwest corner. (You can't just go around the parapet as it's blocked.) Turn right at the top and go through the teleporter. Flip the switch in the middle of this passage, then teleport back to where you were and the bars are now open, allowing you access to another courtyard.

Through where the bars were, down the lift in front of you, turn left and go north, and you will come to three teleports. You need to go through the left (westernmost) and middle ones, in either order.
 * Through the left one, and press the switch then return. You will land at (E); go right and right again, and if this is the first of the two actions, continue to the end and right again, through the odd-shaped tunnel and back to the lift. If it is the second of the two, turn right at the first gap (G) and drop down into the room below; to your left is a now-unbarred teleporter.
 * Through the middle one, and press the switch then return. You will land at (F); go straight ahead, and if this is the first of the two actions, go right and around to the lift. If the second, go left and around to (G), and drop down and go through the teleporter.

Go straight ahead and drop down through the hole, then go through the dragon door. Approach the door ahead, and you will find yourself in The Lab. If you are on the "bad" walkthrough path, after returning from The Lab retrace your steps to the entrance teleporter (which isn't difficult, now that most of the doors are open) and return to the Oracle.

Secrets

 * After going through the middle teleporter of the three, the blockage on the parapet of the first courtyard is removed, revealing a slide door (H). Go through this and the teleport and press the switch, then go through the next teleport and you will land on the right (easternmost) teleporter of the three. Turn around (being careful not to move otherwise) and you will find that the door has opened; go in for medical supplies and ammo (and 100 gold, although this is useless at this late stage of the game as there's nowhere to spend it).
 * Top left hand of map is a column with a receiver teleport pad. To reach it, use portal in nearby large building (it's on the main lowest floor). Once you are on the receiver pad, the wall nearby is fake and will allow you to jump through it.

Trivia
There are three exits from the south end of the level: The first two are mutually exclusive, since the door to the Temple exit doesn't open unless you enter this level that way, and doing so closes the door to the Factory exit. The third is unreachable without cheating, since to reach that teleport line you have to cross the teleport line to the Factory.
 * 1) The good-path exit from (and to, although you won't need to return) Factory: Manufacturing.
 * 2) The bad-path exit from/to The Temple of the Oracle.
 * 3) South of the good-path exit, another exit to the Temple.
