City of the Serpent – Go to the Crimson Fire

Follow the path down to the east. Jump across the gap and continue to the end.

Jump off the wooden platform and grapple-swing over to the climbing wall. Axe-climb up and around to the right to reach the ledge above.

Cross over to the other side and jump to grab the horizontal bar. Lara swings out onto a wooden beam...

...which collapses beneath her. She manages to grab the ledge below. Pull up, jump across the next gap...

...and climb the steps. Continue through the angled opening ahead on the right.

A Trinity helicopter makes a close pass, firing at the Yaaxil on the bridge below. As the helicopter passes, follow the ledge down to the right...

...and walk out onto the jutting branch.

Jump out and grapple the left end of the craggy wall on the T-shaped stone structure ahead.

Climb the cable, latch onto the climbable wall, and axe-climb to the right.

Jump past the gap in the climbable surface and continue climbing all the way to the right.

Rappel down as far as you can.

Swing back and forth to gather momentum then jump to grab the ledge at the base of the structure ahead. Pull up and move through the building to the other side.

Use a rope arrow to run a zip line to the next building and slide down.

Lara meets the Yaaxil leader, who she now understands is the Crimson Fire—Unuratu's counterpart, the Chak Chel to her Ix Chel. Lara manages to convince the other woman that she is capable of taking Unuratu's part in the ritual. The Crimson Fire gives Lara a mask symbolizing Ix Chel, and together they approach the temple.
