Part 27

To defeat Crying Wolf, stay upwind and use the Solid Eye's (a type of HUD (heads-up display — the on-screen icons showing health, ammo and the minimap) element) night vision to spot her heat signature. Avoid staying downwind, as she can track you by scent.

Engage Crying Wolf from a distance using a long-range weapon with a scope, such as the SVD or Mosin Nagant. Damage can only be inflicted when her exposed body is visible as she prepares to fire her rail gun.

Initially, Crying Wolf is located on the opposite side of the Communications Tower. Crawl and use the camera to search the area thoroughly.

Once Crying Wolf is spotted, check for any nearby Haven Troopers and eliminate her. Her subsequent location will be easier to track.

After defeating Crying Wolf, she becomes Crying Beauty. Maintain distance, as her grab attack causes damage until you can break free.

In the Blast Furnace area, head west along the first catwalk and shimmy across a narrow ledge.

Proceed down the stairs and check the locked door in the northeast corner. The exit is in the northwest corner.

Return to the third floor and drop to ground level, avoiding Scarabs (small, rolling enemies).

Use the elevator to descend to the B5 basement. Consider using a chaff grenade (an item that disrupts enemy sensors) if you encounter difficulties.

In the Casting Facility, stay inside the elevator to avoid detection by Gekkos (robotic enemies).

Follow the south wall east, then cross to the western side before entering the northern portion, keeping track of the Gekko's position. A second Gekko may be present on the east side in more difficult games.

In the northern half, navigate past Gekkos and Scarabs. Stay on the west side and use mechanical equipment as cover (press the cover button to crouch behind walls or objects).

Wait for patrolling Scarabs to finish scanning the west wall and move away, then quickly run across and dive behind equipment for cover. A ration (healing item) is located between a piece of equipment and the wall.

Cross back to the eastern side, waiting for the Gekko in the center to move south before climbing onto conveyor belts. Avoid being seen by Scarabs on the other side.

When the Scarabs are facing away, jump down and run to the exit. Climb down the ladder and proceed through the door to the Underground Base.

In the Underground Base hallway, crawl through a broken gate.

Follow behind a Scarab rolling on the catwalk, waiting for it to move away from the entrance to Rex's holding area.

Duck under a Gekko on the wall to avoid detection. The door to the elevator will not open if you are in an alert phase (detected by enemies), which also triggers an endless swarm of Scarabs.

If the area is clear, enter the Underground Base to prepare to fight Vamp.
