E2M2: Filtration Compound (Doom the Way id Did)

E2M2: Filtration Compound is the second map of The Shores of Hell in Doom the Way id Did. It was designed by Michael Mancuso (esselfortium) and Xaser Acheron in the style of Sandy Petersen and John Romero.

Essentials
Notice the set of lift floor textures in front of you. Move forward and to the left to a door. Inside this room, find the switch here and it should lower those textures as stairs. Go down these steps following a path. You can find a box of shells in a side room containing blood and a lost soul. An armor is in the next big room. A little north and east of that is a switch to open the rest of the passage. Go through here, up the stairs and across the walkway overlooking the blood. In this big area, if you take the stairs, you will find the blue door and also see the red skull key in the window. You can get a secret in the southeast corner of this area too. Otherwise head westward, into another pool of blood where you can find another box of shells. If you go north, you can get another secret, otherwise, head west again. In the next chamber go north up the stairs and follow a path to a switch. Pressing it causes a ledge to rise in the room you see through the window. Now you need to cross the blood into that area. You can grab the radiation suit here, or the one right next to the blood. Either way, go west and then up the spiral staircase. Then climb the next spiral staircase to the south. You will find a room with a blood pool, another path, and a switch. Press the switch, and then take the other path if you want to, you will get some ammo for it. Otherwise, go back down the spiral staircase again. Now head right through the newly opened passage, through a small tunnel. At the end is another room with a spectre and the blue skull key. Grab it and drop down. You should be right next to the blue door, so open it.

Cross the walkway and you will find two radiation suits, so pick up one and drop down into the blood going west to the next door. Take this spiral staircase down to a T-shaped walkway. If you go to the center of the walkway, the part from where you came will sink into the blood. If for some reason you want to go back, restore it by pressing the switch on the northern walkway. Go into the C-Shaped spiral staircase to your west, either by using the walkway or by dropping to the south to the base of the staircase (by the way, if you drop to the north, it looks like you cannot escape, but you can by moving around a bit and the walkway will lower. Do note that you cannot make it rise again however). If you go west of the C-shaped staircase, you will find a three-pronged fork. Go left to a teleporter, you can get a secret this way, as well as a medikit and rockets. If you go right at the fork, you might find a secret wall, which has a switch which helps you if you go straight across the door into a marble room. In this room, if you approach the pillar with the beating heart, the nearby wall will lower revealing enemies; if you found the secret switch here earlier, you also can access a teleporter and two secrets if you look long enough.

Back at the C-shaped staircase, take it all the way to the other end into the next room. In this room, go up the stairs to raise paths in the blood leading to a plasma gun and a rocket launcher. However, you can only choose one gun to take, as the other weapon's pedestal will rise when you take one of them. When that is done, keep heading east and you will eventually stumble upon the red skull key. Take the lift up to get it and press the switch here to raise a bridge up so you can cross over to the red door. Behind this door, the room on the left has a rocket if you want it. Otherwise follow the path westward. You will have to drop down into a blood area at one point. Should you want to go back, the switch by the door lowers the walkway, and you can use the lift in the northeast. Otherwise, go through this door and the next one to leave the level.
