Part 32

Dive down and swim through underwater openings. Surface in the next area and crouch-walk past four flame vents in pipes. Continue crouch-walking past an underwater roller gadget and swim to the right to surface.

In the room with a first aid station, get back in the water and swim on. Surface in a room with three conveyor belts and mashers. Turn left, jump onto the ledge, and shoot the bullsquid through the window.

Cross to the opposite ledge to get a .357 Magnum. Enter the bullsquid's room to find a first aid station, two C4 satchel bombs, and two armor batteries. Grab both satchels.

Go along the ledge to the conveyor control panel. Hit the middle switch and quickly run back out to avoid the bullsquid.

Go to the window in the bullsquid's room with a button panel. Observe the timing of the two mashers above the rightmost conveyor belt. Hit the button when both mashers are up, then quickly run to the conveyor and crouch-walk under the mashers.

Once past the mashers, uncrouch and run along the conveyors until section c2a4c loads.

At the end of the conveyor belt, drop onto the next one. Avoid the horizontal piston-style and vertical stomp-style mashers by studying their timing.

Crouch-walk past a spot beyond the last masher, then drop onto the conveyor belt below. Move against its direction of movement until you can cross to a parallel conveyor belt.

Shoot out a laser tripmine ahead with the pistol.

Walk along the conveyor until stopped by a cross-conveyor. Crouch-walk under it.

Get out C4 satchels, toss one onto your conveyor after quicksaving, and detonate it when it reaches the corner to blow up the tripmine around the corner.

If the tripmine is still there, quickrestore and try again.

Once the tripmine is eliminated, go into the big room with large rollers. Jump between conveyors on the left and right to navigate past rollers.

Crouch down as you approach the tunnel the conveyor is going into, then crouch-walk forward until you reach the next room. Quickly strafe right off the conveyor into a corner.

Wait for the mash-jaws in the middle of the floor to open, then run forward next to them. When they close, crouch-walk onto them and drop down when they open.

On the conveyor belt below the jaws, turn and move off the side onto the metal walkway. Walk to the ladder and climb it.

Go down the red-lit corridor until you reach the 'Questionable Ethics' chapter.

At the end of the red-lit corridor, climb the ladder as far as you can and bash the grate.

Turn around on the ladder to face the nearest houndeye. Edge up the ladder until you can toss your last C4 satchel into the houndeye group. Climb back down and detonate it.

Climb up the ladder and into the room above, ready to whack any surviving houndeyes. Grab the box of .357 ammo.

Go through the open gate to find a first aid station near an open door.
