MAP10: Onslaught (The Plutonia Experiment)

MAP10: Onslaught is the tenth map of The Plutonia Experiment. It was designed by Dario Casali and uses the music track "Demons On The Prey" from Doom. In the PlayStation version of Final Doom it is the final level.

Secrets

 * 1) A ways into the level you will make it to a grey brick sewer-like area. In the tunnel to the right are two paths branching off to the left and right; go into the right one and open the misaligned wall to the left to get some goodies.
 * 2) After passing through the sewer area, you'll arrive at a beige-walled computer room. There is a combat armor resting atop a CPU block in the corner of the room. To lower it, walk up the stairs leading outside. When you reach the top, the wooden board gating the way will lower, but rather than passing over it, return back down to the computer room and quickly grab the lowered armor.
 * 3) After making it back outside once you've passed through the sewer area, there will be a sunken stairway leading down then back up to an earlier part of the level. At the lowest point of the staircase, press the use key against the left (west) wall to lower the ground on both sides of the staircase. The far end of the right (east) side (opposite the wall you pressed to lower the floor) has a hidden alcove in it.

Routes and tricks
You can cut out the sewer area and the yellow skull key entirely by accessing the red skull key via the window rather than the traditional route.

The yellow skull key door has two "posts" indicating that it requires the yellow key immediately outside. Use the steps to get on top of the post nearest the window; then strafe-run through the window to get to the red skull key.

This trick was used by (at least) Juho Ruohonen (ocelot) in the record below.
