Tomb Raider: Underworld - Full Walkthrough

Chapter 4| Southern Mexico

- Ride the bike down the obvious path until the cut-scene shows you an object through a window of a stone temple.

- Use the series of ledges on the stone pillar in front of the temple to get onto, and then scale, its front wall. Grapple onto the gold hook and then abseil down the front of the building. It will pull a switch opening a door to your right. Wall run across and grab the ledge and pull yourself up and into the temple before it falls shut again.

- Inside, pick up the Jaguar Head on the plinth ahead. Now exit the building by chimney jumping into the room above and then using the ledges to work your way to the ground outside. Beware of a black panther attack.

- Hop back on the bike and continue past the temple through the ruins and down some steps through a long tunnel. As you emerge from the tunnel head up to the temple ahead and park up. Cut-scene.

- You'll be standing facing a large open area, in front of you is a lever attached to the ground in the middle of a large circular stone structure with a skull on a plinth next to it. Place the stone Jaguar Head into the top of the central lever. Now the puzzle.

- The aim here is to line up the three black sections of the stone circles (Mayan Calendar). When Lara operates either lever the camera shifts into the same position. Our directions are given from this angle - with the camera facing her.

1. Line up the two outer rings so the black sections face away from Lara towards the middle of the open area, using the central lever. A clunk noise will be heard when this is done.
2. Now use the skull lever to disengage the smallest central stone circle (push the column as far left as it will go). This will also move the outer ring.
3. Line up the middle ring with the second largest ring, which will still be in position.
4. Finally, return the outer ring to its position by pushing the skull lever back into position again. You'll need to do the exact same thing again on another Calendar which is in the structure opposite you.
