E4M1: Hell Beneath (Doom)

E4M1: Hell Beneath is the first map of Thy Flesh Consumed in Doom.

Secrets

 * 1) Drop into the nukage pool ahead of you at the start of the level. Press the use key on the end of the platform to the right to lower it, exposing a hidden tunnel with a rocket launcher at its end. Open the wall to the left of the rocket launcher to reveal a room with a pair of teleporters. Each takes you to a corresponding ledge near the level's beginning.
 * 2) In the room behind the red door, make your way left around the rectangular structure and press the use key on the torch. This lowers the rectangular structure, uncovering a hidden "NIИ" logo. Walking over the logo triggers the secret and unleashes some Barons, and may also trap you inside for a short time. Note: The area surrounding the "NIИ" letters is tagged as a secret sector, as opposed to the letters themselves, so this secret may be a bit tricky to register.
