SECRETS

E2M1:

1. At the start you'll see a locked door to your left. Go North to the fake teleporter, take the lift down, run to the facing wall (with the lone STONGARG texture), press it and run back to the lift before it rises again. Run back to the start area to find the door to the right has opened. Take the stairs down to the secret area.
2. Across from the pentagram (with the shotgun at skills 3/4/5) in the area near the blue key, you'll see a pillar on the right. Pass it and go around the curve, cross the blood-moat, and press the switch against the wall. It temporarily lowers the pillar, which teleports you to the secret area.
3. After you pass the pillar with the blue key you'll cross the blood-moat and see a teleporter. Take the teleporter, but when you reach your destination *do not jump down*. Instead, turn around to see a slight inset in the wall. Press the wall to open it and pick up the red key to the area with the blue armor. If you jump down without getting the key you will not have another opportunity to get the key.

E2M2:

1. In the crate area near the start, head South all the way and turn left at the third gap in the crates. Turn right and you'll see a crate with smaller crates to its right. Climb atop the crate and press on the crate with misaligned textures to lower it, then jump onto the secret ledge.
2. Go through the circular area at the center of the map, then through the door at the South. Turn left at the top of the steps, go to the far chamber, and find the odd texture on the West wall. Press to open the door and enter the secret area.
3. Go to the end of the secret area in 2, above, and look for the misaligned texture on the right. Press the wall to open it, and enter the secret area.
4. Do down the steps of the secret area in 3, above, and look for the misaligned texture on the right. Press the wall to open it, and enter the secret area.
5. Use the radiaion suit in the secret area in 4, above, and run to the nukage passage to the East. You'll pass a barred passageway with a blue armor behind, and a little ahead you'll see a slight recess in the wall. Press on the wall to open it, and pick up the armor in the secret area.
6.  In an area near the crushing ceilings there's a room with a plasma rifle visible atop a pillar. Outside that room is a recessed area in the wall with an odd texture. Press on that recessed area to lower it, and then press the switch behind to temporarily lower the pillar, which is the secret area.
7. In the passageway with the crushing ceilings, the wall at the third crusher has a skull switch. Press it to temporarily open the bar on the wall across. Enter the secret area.
8. After passing the crushers you'll enter an area with nukage, and at the far end is a drain. Step on the drain to lower a lift back across the nukage; the lift is the secret area.

E2M3:

1. In the first area to the right when you start the map you'll see armor behind bars. Walk around that wall to the other side, and look for a differently textured walls. Press on the wall to enter the secret area.
2. In the area with the rising & lowering floor sections, walk towards the candelabra at the South end. You'll hear the nearby door opening; run North and then West to get through the door before it closes. [You'll need to time it properly because of the rising floors.]
3. There's a pillar with a berserk pack outside the area with the barrels. In that room there's an alcove with a switch, which temporarily lowers the pillar.
4. On the way to the steps leading up to the blue key there's an oval-shaped room to your right. Press the lion's head that's not lit up, and enter the secret area. [The radiation suit in there allows you to get to the rocket launcher through the blood river without taking damage.]
5. After going through the blue key door you'll eventually come to a dark area. Find the pillar in the North-East quadrant with the "Poison" sign. Press it to enter the secret area and pick up the radiation suit.
6. When you cross the final nukage area you'll see a doorway to the right. Run all the way to the far end to pick up the plasma rifle.

E2M4:

1. At the start, turn around and open the door in the blinking-light doorway to enter the secret area.
2. Upon entering the large hall from the start area, head North and take the lift up. Go around and look for the misaligned Tech texture on the other side. Press it to open an area with a switch. Press the switch and run to the North-West corner of the room with the pillars; one of the pillars will have temporarily lowered. Run inside, press the switch on the wall, and enter the secret area.
3. Use the radiation suit in Secret 2, above, to run to the nukage channel to the South-Western part of the map and press the gargoyle-adorned section of the right wall to open a secret area.
4. Further in that nukage channel there's a switch on the left wall. This will raise the bar to the secret area at the North of the oval-shaped nukage area.
5. In the area with the crushing ceiling and the chaingun, an area opens up to the East. Look for a misaligned texture and press it to enter the secret area.
6. After you pass through the yellow-key door, turn left and go all the way around the circular area. Look for the gap in the left wall, drop through, and teleport to the chainsaw at the center of the circular area. Return to the gap in the wall, drop through again, and go around to press the switch that lowers the plasma rifle pillar. 

E2M5:

1. When you pick up the chaingun a couple of alcoves will open. One of them has a switch that lowers the two pillars near the chaingun area.
2. Go into the room behind the chaingun area and walk straight into the alcove ahead. To your left is a door, behind which is a secret chamber marked by a different texture (gargoyle vs. skull). That door will temporarily open when you walk into the alcove. Run to get inside the secret area before the door shuts.
3-4. [This is a 2-part secret.] From Secret #2, above, head East, pass the room with 3 pillars, then take the curving corridor South. Stepping into the "H" shaped room from the curving corridor will lower a lift behind the door to the right. Ignore it for now, and enter through the door to the left. There are three alcoves on either side, and the wall outside the last alcove to your right has a different texture. Press it to raise the steps behind the grate. Go back out, activate the lift as descibed above, run through the door to the left and onto the lift. [It helps to open the door first, step backwards quickly, trigger the lift, then run forwards through the open door.] Climb the stairs you raised before, take the teleporter, and press the switch at the other end. It opens the adjacent door that leads to the secret level, E2M9.
5-6. [This is a 2-part secret.] After you've returned from opening the door to the secrel level, go back North to the room with the 3 pillars. Take the first door to the right and look for a support pillar with a Satyr texture. Press that to open a nearby door in the nukage. Then go West around the circular stairway to the top, notice the radiation suit behind a bar to your right, turn left and stop in front of the door at the end of that curving passageway. To the left is a misaligned texture - press it to open a door, step on the teleporter and it'll bring you to the room with the radiation suit. Press the switch behind to open the bar, pick up the rad suit, and find the nearby nukage tunnel. As you reach the end of this tunnel you'll hear a door opening in the area where you pressed the Satyr switch. Shoot the switch inside and it will open a door further along the nukage area, allowing you access to the plasma rifle.
7. Return to the area you opened while going through the first nukage tunnel above. This is a secret area.

E2M6:

1. Go past the dark, wood-heavy area, and enter the computer room on the left. The far wall has a computer panel with a slightly misaligned texture. Grab the light amp goggles in the secret chamber.
2. To the left of the red-key door is a door leading to a corridor. On the left is a vented panel; press that to reach the secret area.
3. When you enter the area with the plasma rifle and several doorways, take the corridor to your North, and run up the stairs, open the door and dart to the lowered lift to your left, and grab the soul sphere. Alternatively, after you've cleared the red area below and take the circular stairs back, run up the stairs, jump down into the room with the soul sphere pillar, zip around the central pillar, and dart onto the lowered lift.

E2M7:

1. From the start take the right corridor around and pass the blue key door to your left. Go around to the room with the "Spawning Vats", and notice the first one to your right has a slightly different texture at the end. This "door" requires a blue key, so return here when you have the blue key and enter the secret area behind.
2. After you get the yellow key and return to the outdoor nukage area to the South-East, you'll open the yellow-key pillar to the plasma rifle. Further in, the wall to the right has a skull texture. Press that wall to open the door to the secret area.

E2M8:

1. After you've pressed the second skull switch in the outdoor arena (which lowers the pillar with the chaingun) go around to the back side of the wall with the switch. There's another switch there. Press it to lower the platform with the SoulSphere & Blue Armor in the chamber in the Southernmost part of the map.

E2M9: No secrets.
