E2M1: Deimos Anomaly (Doom)

E2M1: Deimos Anomaly is the first map of The Shores of Hell in Doom.

Walkthrough
Go past the teleporter to get the blue keycard. Come back and teleport.

Go around and take the next teleporter. Walk forward and click the skull switch on your left (south) to lower the wall ahead.

Go west and then around to your left to the blue door. Go through and teleport.

Go nearly to the far wall, then turn around to see a red switch on your left facing southeast. Click it to raise some stairs just beyond. Go up the stairs and click another red switch. This opens up a teleporter back near the first switch.

Teleport yet again. Walk forward to lower the wall in front of you and reveal the exit door.

Secrets

 * 1) As you approach the second teleporter, click the switch on the eastern wall. Then click the switch that rises up behind you. A hallway to the north containing the red keycard will open.
 * 2) Click the switch on the other side of the short wall that rose up with the previous switch on it. This opens a teleporter way back where you found the blue keycard. Take it to a secret room with a plasma rifle.
 * 3) After you take the teleporter near the red keycard, there is a skull switch to the left, facing west, of the skull switch that lowers the wall ahead. This other skull switch raises the wall it is on to open a teleporter room. Teleport into a long hallway containing health potions and spiritual armor.
 * 4) Go through the red door to find a computer map.

Routes and tricks

 * If you are going for 100% secrets, take the first teleporter when you first come to it. After clicking all the switches at the end of the hallway, teleport back to get the blue keycard and teleport to secret #2 at the same time.
 * It is not necessary to click the switch that raises the short wall with switches on both sides. Just click in the air as if the wall had already risen.
 * You can collect secret #3 while waiting for the wall ahead to lower.
