Tomb Raider: Underworld - [Southern Mexico] - The Midgard Serpent - part 1 - game guide, walkthrough, secrets, game tips & strategies

You are inside, just near the motorbike. Sit on the bike and go straightforward in wide corridor.

From time to time, you will pass through wooden jump platforms.

Be careful because one of them is incorrectly directed. Stop before the hole and jump on the lower bar. To get to the higher one, you will have to recoil from the wall. When you get there, jump on the visible ledge. If you do this the jump platform will be misplaced to correct position.

Ride further. You will reach the big room with statues of people sitting on the throne. Leave your motorbike and kill big spiders.

Under one of the sculptures you will find the machete. Take it and place in the hand of the sitting character.

Look around and try to locate stairs which are visible on the first screen. Go up, and take the second machete.

The statue to which belongs the machete is located just near the stairs. Place the machete in appropriate place and turn the statue 180-degree.

When you do this the door above the stairs will open. Go inside new room. You will see mobile stone blocks along it. Approach them and run to the other side when the passage is open.

Take the symbol from the altar and turn around. Slightly above stone blocks you will find another symbol which has a metal roundel. Grab it with hook and move more or less to half of the room.

For a few seconds the passage will be open. Run to the symbol in central part of the room and climb on it. When the passage is open again, run outside.

Turn the next statue around 180-degrees. Do this clockwise. You will open another door. Unfortunately this time stairs will be damaged and you will have to sweat a little.
