Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Secrets
1. Opposite the area with the Invulnerability sphere, in the southeast of the main map, there is a stage, which has a plate with a Baron's face on it. Open it, and you'll find Combat Armor inside.

Throughout the map, there are five hidden Commander Keens, each of which has a skull switch behind it. Each skull switch, when shot, opens a tomb at the northeast of the main map, near the starting area. There are six tombs, each with a Keen inside (one is already open), and each one also has a skull switch behind it. Shoot all of the switches (preferably with the Super Shotgun, as the other weapons may not be able to reach the switches), and it will open the way to a non-registered secret, ice-covered area with a message from Plutonia 2's developers, countless Health potions, and three Soul Spheres.

Routes and tricks
The exit is the gullet of the dragon's mouth in the northeast of the map. Although you can plainly see it, there is a door in your way which doesn't open until you pass through "The path through Hell" in the southeast (which requires all three keys to reach). However, you can also lure an Arch-Vile out of the curved tunnel in the north-center, and Arch-Vile jump your way to the platform just beyond the door. (You must straferun to make your way up, the gaps are too big otherwise).

Because you need the red key to reach the yellow key, and the blue key is closest to "The path through Hell", it might be advisable to get the red, then yellow, then blue keys when performing a UV Max run.

The teleporter at the end of "The path through Hell" leads to the room in the northeast where the Spider Mastermind is, making the the Spider Mastermind easy to telefrag.
