Beyond the door you opened with the RED PASS CARD (shown in the last section), is a ROOM WITH A RAMP AND METAL LEDGES. If you rush into the next room, Lara will be ambushed by 3 more rig workers (9-11). But if you proceed with caution, you can take them out one at a time.

First, draw pistols and step into the doorway without going any farther. Lara will target the enemy on the catwalk (9) to the left, and you can shoot him without taking any damage or triggering the other enemies.

Then enter the room and immediately take a running jump across the shallow pit on the left to land on the catwalk. An alarm starts blaring, but there's nothing you can do about it, so just go on about your business.

Two bad guys with clubs (10-11) appear. One materializes inside the room; one enters through the door near the RED LOCK. They can't reach Lara on the catwalk. So take your time and use pistols to conserve ammo.

Afterward, loot the bodies for a small medi pack, flares, and shotgun shells (19-21).

Locate the movable box at the right end of the catwalk where the first bad guy fell. Push it once.

Go around to the ledge on the opposite side of the box. Climb up and pull the box once.

Then return to the other side and push it once more so it's sitting on the protruding ledge.

Climb onto the wide, metal ledge in the middle of the room. Take a running jump to grab the edge of the movable box and pull up.

Step back to the outer corner of the box then jump into the doorway above (or jump and grab the edge then pull up).

When you turn the corner a thug with a gun (12) starts shooting at you.

Kill him and take his shotgun shells (22). Continue down the ramp into the next room.

There's a closed trapdoor in the floor and a door with a GREEN LOCK on the right, but you don't yet have a key card for it. Pull the switch on the opposite wall to pump water from one of the two pools in the next room into the other.

Before...

...and after using the switch.

Return up the ramp to the room with the movable box. Safety drop to the floor. Climb onto the wide ledge and swim across the pool to the area with the big orange tanks.

Jump over the pipes on the right to land on the metal ledge near the wall. Jump up the slope and pull the switch...

...to open the trapdoor in the room with the GREEN LOCK.

Swim back across the pool and return to the room with the GREEN LOCK via the movable box and elevated passageway.

Drop through the trapdoor.

Slide down the long slope and stop at the edge of the catwalk in the next room. There's water below, so Lara won't die, but you don't want to fall in yet. (If this happens, there's a note in the next section about what to do.)
DARK MODE: I plan to add optional dark mode for these pages, but my current priority is updating the walkthroughs. Meanwhile, may I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's official add-on/extension site.)
