Tomb Raider Walkthrough Part 1 – So It Begins, Force of Will

After the Endurance falls to ruin and Lara is washed out over to the beach someone comes up behind her and clubs her. When Lara comes to she is suspended upside down and needs to escape from whatever fate may be in store for her. Use the Movement Stick to swing to the sides to get Lara's, “cocoon” moving. After that start swinging toward the beam you set on fire to get Lara down.

After landing and getting skewered a little she is back on her feet. Hit the prompted button to yank out the steel rod. Now stumble over to one of the torches nearby in the next room. Lara will grab it, adding it to her inventory. The torch is a simple thing to deal with. Near a source of fire, just hold the Action button to light it. To extinguish it, just hold the Dodge Button.

Go forward, over to the right and down the passage. You will come to a wall of planks and barrels. Approach it and hit the prompted Action Button to burn out the debris. Go forward and Lara will automatically squeeze through the tight spot. The running water will extinguish your Torch.

When you get into the next room you are introduced to the Survival Instinct. You will see a number of things highlighted in gold. Start by going over to the brazier with the flame in it to relight the torch. Now turn to the left to jump and climb up onto the nearby ledge. Turn to the right on it and use the Torch to light the nearby cloth on fire. This will lead right to a gas barrel that will explode shortly after and clearing your path forward. Now head over to the cleared ledge and move forward into the small opening. Lara will automatically crouch and start moving through it. You will be prompted to shake a man loose who attempts to pull Lara back to where she came from. Just continue through the opening after that.

Force of Will
Head on forward through the deep water where Lara's head is just above water with the torch. Get on through to the next little cutscene to enter the next room. A splash of water will extinguish the torch yet again. Time to find a way out of here before the Tide gets too high.

Head over to the right and through the flow of water. Head over to the ramp on the right and you will find another source of flame. Light the torch and continue on forward. You will find something, a Diving Cage, held suspended by 2 lengths of rope. Light each in turn to raise it and lower a barrier into the water. Some of the boxes will get trapped here. Light them on fire.

Now head over to the walkway and take it up and around until you are nearby the Diving Cage. Jump over to it. This will raise the barrier and bring the flaming debris up and into a cage to your right. Jump out of the Diving Cage turn elevator and head back around to the top of the wooden walkway. There is a second cage you can interact with using the melee button. This will launch the burning crates and barrels down into the mines and fuel barrels blocking your way out. This will blast away the debris and clear the next part of the path out.

Start down the path and over for the path to the right, toward the light. The path will give way beneath you. Slide to avoid the sides and press forward when she lands. Start forward and jump onto the rock that is slowly sliding in front of you. Run across it and jump to the next few ledges. The man will appear again and grab Lara. Wiggle the Left Stick to break free then hit the melee button when prompted to break away from him. Just keep going forward. When prompted, 2 button will appear. Hit them in alternation to make it to a Quick Time Event. Hit Left on the Left Stick to avoid a rock. After that continue the scramble up, after dodging a second rock by moving to the right. Then she is free.
