Episode 1: Dimension of the Doomed

E1M4: The Grisly Grotto

1 - Through the door at the start there is a set of spiral stairs. On the left and right at the top are two red symbols. Shoot them. The celing will fall, revealing a yellow suit of armor. Sometimes you are able to crush the knights below with the celing.

2 - From the bottom of the stairs, go through the passage. You will come upon a deep lake. Get the biosuit. Dive down andhead beneath the structure. Surface and wander around until you get the silver key (no, I'm not going to guide you through the whole level). Jump off again. Halfway down on the right wall is a tiny passage leading to a set of rockets.

3 - From the pier with the silver key. Jump off and swim in the direction of the pier. Surface on the other side. Go through the door and to the left. Follow the passage. You should reach a small body of blue slime with a bridge over it. Go to the end of the bridge and ride the platform up. Step on all the touchplates. Two doors wil open in the walls. Enter both and press the buttons. The game should tell you that a secret cave has opened. Jump onto the bridge and head back out to the deep pool where you got the silver key. Along the right wall of the cave will be a large, bright circular opening. Enter it. Swim up. Inside a little room is a grenade launcher, health, and a slipgate to the secret level.
