top of the elevator and follows Willard.

Turn right from the start and climb into a crawlspace, emerging in a hallway.

Run down the hallway, turning corners as doors open. Continue past the section with no doors.

Quickly kill the Mutant Crawler to the right and press the button in the doorway to turn on the lights.

Secret #1: Climb onto the roof of the control room. Head to the back right edge, crouch, and hang over the edge. Shimmy right until Lara gains a foothold on a ladder. Climb down until Lara's feet are at the edge of the building. Back flip off, rolling in mid-air, to grab a crawlspace behind you. Inside, find a Small Medi-pack and Grenades. The door leads to Secret #2, but it cannot be accessed yet.

Shimmy left and pull up into the space. Kill the Mutant Crawler.

In the next room, climb onto the walkway for the Crowbar.

Optionally, climb down into the pool for the Rocket.

On the right wall after entering, there is an opening. Stand on the small snowy ramp to the right of the opening and jump straight up to grab an invisible crack.

Shimmy left and climb up into the opening to find a button. This enables access to Secret #2 later.

Head back to the entrance. Run to the top of the snow heap to the right of it. Turn left and use a running jump to the snow pile ahead.

Make an angled jump, veering right in the air, to make the next ledge.

For the final jump to this area, make an angled jump, veering right, and grab the ledge.
