Geothermal Caverns - Rescuing the Captives - Part 1

Stay quiet and hidden behind the low wooden wall as you survey the situation. Lara's friends, Alex, Jonah and Reyes, are caged inside a junked helicopter suspended from the ceiling. Three Solarii stand guard below. Reyes is taking none of their shit, and Lara isn't about to either.

Stealth isn't quite as important here as before. If you alert any of the men, only one extra enemy will appear. But if you want to take them out on the quiet, start with the guy on the far right. When he moves off...

...you can kill him with a silent headshot.

Then take care of the demo man...

...and finally the third man on the steps.

If a fourth enemy appears, he'll be off to the right. You can use the wooden wall for cover as you finish him off.

It's actually a little more fun if you do this combat with some flair. Then when Lara's friends start cheering about how awesome she is, it'll be more satisfying.

Afterward, loot the bodies and pick up as many arrows as you can carry. There are 3 bundles of arrows in all: one near the wall where you hid, another leaning against the rocks to the right of where the men were standing, and another off to the far right. (I haven't pictured these since they're pretty obvious. Use Survival Instinct if you're having any trouble spotting them.)

Go up the steps where the third man was standing.

Crank open the valve and move out of the way so you don't choke.

Stand back and use a fire arrow to ignite the gas.

This frees the first counterweight securing the cage but also sets off several other small explosions, weakening the floor below the cage.

Move up the stairs and around to the platform on the left. Grab more arrows if you need them.

Then jump onto the dangling counterweight platform. From there, jump to grab the top of the cage and pull up.
