The first thing you'll want to do during this mission is take out all monsters in the first room. After doing that you'll want to swim through the underwater tunnel and take out all of the enemies in this room too. Search for the elevator in the water and ride it up so that you can hit a button and make a bridge to the central room.
Inside the central room you'll find a Rocket Launcher which you'll definitely want to get. Go straight through the central room after grabbing the weapon, you'll be lead to a small pit with a button inside of it. This room is also where you'll find Secret #1. Hit the switch, defeat the enemies and then exit this area via the opposite hallway. Continue straight through the central room again and hit another button on the other side.
After hitting the button you will ride an elevator up; grab the Super Nailgun up here and then fall down the hole on the other side. You'll find yourself in the most memorable room of this entire level - the floating platform room. This room is very confusing at first but it's actually pretty easy to navigate. Your goal is to ride around the elevators here and shoot the various buttons that you come across. Some of the buttons you shoot activate additional elevators which allow you to progress deeper; others will crush enemies in a certain cubby.
Your ultimate goal is to raise the large solid platform nearby where we first entered this area. To do that, you'll have to ride numerous platforms around the room until you can reach the furthest button to raise this floor. On your way to that button you'll come across Secret #2 and Secret #3, both of these are found in the same location.
In the area after these secrets you'll find a small hallway with a button on the floor, shooting this button will activate the platform next to it and raise the platform I mentioned earlier. This lets us access the final platform which leads to an elevator that takes us to the end(s) of this mission. If you're lost or having trouble figuring out where to go fall into the water below and take the teleporter back up top. This will put you exactly where you originally entered the area, from here you can jump to the platform shown below and reach the exit.
Hit the button and you'll ride an elevator up to a medium sized room with some lights on the ceiling. Secret #4 is found inside of this room, shoot a light to gain access to it. After clearing the enemies inside of this room you'll come to a large room filled with lava. Down the stairs you'll find a Thunderbolt, before you can grab it though a Shambler will spawn so be ready.
It's at this point that you can exit this level via the secret exit or by taking the normal exit. To use the secret exit you'll need to jump down a pipe in the lava and go through the portal there. Watch the video I made for this level if you'd like to see what I mean.
For the normal exit, use the portal at the bottom of this area and you'll be taken back to the entrance of this level. The gate that was here originally will now be gone and you can use the slipgate exit that is above your starting point. Like with all of the previous episodes, using the secret exit will take you to the final level of this episode E3M7, The Haunted Halls. Using the normal exit will take you to the next mission, E3M5, Wind Tunnels.
Secret #1
Secret #1: This secret is found above a pit that you need to press a button in to advance this mission. On one side of the pit there will be noticeable stairs inside of the wall - you can shoot the light to make the stairs come out... Or you can jump onto them and climb up them without shooting them like in my video.
Secret #2
Secret #2: In the very large room with all of the moving platforms, you'll find this secret in a small nook. The location is hard to explain in text so I recommend you use my video and pictures, it's far from where you enter the room the first time. Shoot the nook to gain access to it and make sure you get the next secret at the same time! You'll find a lot inside, the Quad Damage power up is kind of useless.
Secret #3
Secret #3: You'll find this secret location in the same exact area as Secret #2. To gain access to this secret you'll need to shoot all four lights in the room that Secret #2 is in. Doing this will open another door and you'll find a Pentagram of Protection inside. Enjoy doing basically nothing with either of these power ups because we have to wait for elevators to get to any monsters.
Secret #4
Secret #4: After the room with all of the moving platforms you'll ride an elevator up to a small room with lights on the ceiling. Shoot the light in the back right that is a different color to open up a room with a Pentagram of Protection. On higher difficulties it's best to do this during the fight if you can.
