MAP03: Poison Sewers (Whispers of Satan)

MAP03: Poison Sewers is the third map of Whispers of Satan. It was designed by Paul Corfiatis, who also wrote the music track for this level, "Base Stalker".

Essentials
Kill the monsters across the gap and drop in to the right, being sure to pick up a radiation suit as you go. Follow this nukage tunnel to the next big room. The northern door can be opened, so take it. In the next room you need to raise a staircase, so head around to the left and open the next door to reach a crate room. Clamber over the crates your immediate right upon entering this room, and head north to the switch. After hitting it, head back into the previous room to see the staircase being raised. Hit the switch here, and then go back to the room at the end of the sewer tunnel to find the other door is now open. Head through this room to the lift, and then ride it up. Follow this simple path until you reach the yellow keycard. When you grab it, closets with imps open up to the sides. Go all the way back to the beginning and take the northern sewer passage this time, opening the bars with the yellow key. Follow this passage all the way to the end where the chaingun is and open the door. Just grab the red keycard here and then backtrack to midpoint of the sewer path where you passed by the red door. Now open this door into a symmetrical room. There are two paths that lead up, but the one on your right does not have a bridge, so take the left one, up the steps to the switch. This raises a bridge for the other path, so take that one up to another switch. Hit this one, and then go all the way back to the beginning of the level. You will find that you have raised a bridge leading to the exit, so get out of the sewer by using the lift and cross the bridge, then press the switch to open the door to exit.

Secrets

 * 1) When you raise the staircase in the room north of the room at the end of the first tunnel, you will also notice a soul sphere on a ledge nearby. The only possible way to reach the soul sphere is to raise the staircase and perform a straferun towards it. (sector 94)
 * 2) In the gray hallway that leads to the yellow keycard, in the northwestern part of the hallway, open the north wall to reveal a computer area map and a berserk pack. (sector 397)
 * 3) In the symmetrical room behind the red door, go straight to the end opposite the red door and a bit to the left. Open the skull wall to reveal a chainsaw and a lot of health and armor bonuses. (sector 385)
 * 4) In the same symmetrical room, on the side to your right where you enter (which does not have a bridge connecting it yet), there is a switch. Make sure you have a radiation suit handy, and press this switch. Now go over to the other end as quickly as you can because you triggered a lift to go down on that side. Go through the passage before it rises to obtain a rocket launcher, a backpack, and some ammo. (sector 366)
