Tomb Raider (2013)/Survive

After the eventful opening scene, you'll gain control. Start by moving right to left (since you can't do much else) for a while; a couple of swings and Lara will create a chain reaction. Swing left to right again and Lara will eventually fall free, though not without a new problem. Hit the button on screen until the splinter is out, then follow the narrow path until you find a torch mounted on the wall. Pick it up and keep moving, holding the torch against the debris using the button prompted onscreen to open up the path. Squeeze through the wet space between the boulders and relight the torch using the fire nearby. Climb up on the ledge to the left and you'll find a peg with a sheet wrapped around it; light the flammable material and wait for the explosion.

Move forward and under the boulders to experience a QTE. Do as the screen says quickly to escape it, and continue on through the waters. Get this far and you'll obtain a new objective: find a way out.
