E3M1: Gates of Hades (No End In Sight)

E3M1: Gates of Hades is the first map of the Woe episode of No End In Sight. It was designed by Emil Brundage (NaturalTvventy).

Secrets

 * 1) To enter a secret room in the northeast part of the map that contains a berserk pack, enter the large hallway on the east side of the map past the blue door. Go to the southwest corner and press on the wall to reveal a passage. Follow it to a room with several tombs. Step on the southeast tomb to open up another passage leading to a red room with many switches. What these switches do is raise or lower three doors at the north end of the large hallway (a hint to this puzzle exists in the building northwest of the starting point; enter and take the right passage to the room with satyr switches, then go up to the marine corpses and shoot the wall to the right to find the correct solution). To proceed, press on the middle switch on the north wall, the leftmost (easternmost) switch on the south wall, and, facing the west wall, the second switch from the right. Once you hit those three switches, go to the north end of the large hallway and across the blue floor, and you should be able to continue to the next room. Check behind the throne for a skull switch, which opens up a passage behind the throne. This passage leads to the berserk pack, but you will have to fight two barons of Hell (only on Hurt Me Plenty or higher) to escape. (sector 9)
 * 2) Once you collect the blue key, enter the building northwest of the starting point and open the blue door. You will see a teleporter puzzle to your left, but attempting to enter it from this side causes you to teleport back. The solution to this teleport puzzle is northeast of the circular room before the large hallway at the east side of the map, where you can push on a side of a column marked by health bonuses to light up the solution. Once you know it, return to the puzzle, then go towards the skull switch at the broken end of the hall. The skull switch does nothing important at the moment, so instead of using it, jump northwest to the piece of the building jutting out. Then look south and make a running jump there to the other end of the teleporter puzzle. Now to get through this puzzle, you should remember the solution you saw, or just start at the first red teleporter you can access, alternating between red and white teleporters. The correct directions are south (onto the red), west, south, west, south, south, east, east, north, and east onto the white teleporter. When you finish this puzzle successfully, a door opens, allowing you to reach the middle hallway. Go all the way north into the next room and press on the northwest corner, where you can access another switch. This switch reveals a segment of wall with flesh on it. Now return to the skull switch from before and press it, which will reveal a lion switch directly north from where you are. Quickly shoot at it, then return to the northern room. The northeast corner of this room now has a passage leading down to where the rocket launcher is, and this is the secret. The skull switch nearby does not lower the rocket launcher, but press it anyways and backtrack to the central hall. Right next to the blue torch, you can climb onto the wall here, then jump onto the rock below. Look north towards the demonic face to find a lever switch. Flip it, then go back to the rocket launcher room where you will finally be able to claim your prize. If you are playing on Hurt Me Plenty or higher, watch out for the two barons of Hell who come in as well. (sector 259)
 * 3) Grab a radiation suit and run across the lava on the west side of the map, through the opening and through a tunnel to reach a soul sphere and some boxes of rockets. (sector 457)
