Z1M2: Nuclear Plant (Knee-Deep in ZDoom)

Z1M2: Nuclear Plant is the second level of Knee-Deep in ZDoom, revisiting the original level with some new twists.

Secrets

 * 1) The room after the green door is a secret. Three rapid fire troopers are inside. From here, you can get to the outside area containing a soulsphere.
 * 2) A blue armor is in the north east corner of the outdoor area mentioned above.
 * 3) In the start room, a chaingun is behind a forcefield. Shut down the reactor to gain access to it.
 * 4) The backpack secret in the start room has remained a secret. The switch no longer works.
 * 5) Before the room with the chainsaw, the armor bonus secret has remained in its original location.
 * 6) Although harder to spot with the different lights, the backpack secret in the dark maze has remained. This time, it contains the green key needed for secret #1.
 * 7) Upstairs after the red door, in the slime room. To the west of this room, there is a small opening visible. Jump into the slime to get under the railing, and resurface to go into the opening. The stairs inside will lead you to an alcove, making the green armour accessible.
 * 8) Also in the slime room, in the north-eastern pit, swim down as far as possible, to find a tunnel. Follow this tunnel until it opens up. Surface here to find a small area with various items.
 * 9) In the south-west corner of the outside area preceding the yellow key room. Using the rocks, jump up onto the brown building extension, and jump down the hole. You will be taken to a storage room. Follow the corridor to find the blue key. You can escape by continuing down the tunnel, and ending up at the blue pillars.
