Geothermal Caverns - "The Pit" - Part 1

There are several tunnels radiating out from this room. Follow the one that leads off to the south. As you move through, a creepy voice prattles on.

The tunnel dead-ends in a small cave containing 2 salvage crates. Open them. Then head back the way you came but stay alert.

Gollum drops down from the ceiling and runs toward you. Shoot him or hit him with your climbing axe to conserve ammo. He won't put up much of a fight. Then continue back to the main cave.

When you emerge from this tunnel, go straight across the cave to the stone ledge with the skulls and candles.

Climb up to find a relic (1/3), a Funeral Fan.

While still standing on this ledge, turn around to face out over the cavern and look up to find a tattered cloth sack (1/6) hanging from the ceiling. Use Survival Instinct if you can't spot it in the dark.

Shoot it with a fire arrow to unlock the Firestarter Challenge: find and burn 6 of these sacks for bonus XP.

There are two tunnel openings on the west side of the cave. Enter the one on the left with the green gas filling the entrance.

Move quickly past the gas into the tunnel beyond. Another pale creature is waiting there. Put him out of his misery. (Here Lara uses a melee strike with her axe.)

Then climb onto the ledge to find another salvage crate and a GPS cache (1/5).

Before dropping down from this ledge, turn and look out over the edge. Use survival instinct to see another sack (2/6) suspended from the ceiling. Shoot it with a fire arrow for the challenge. Then hop down and return to the main cave.
