Burned-out Indian Village
As Nico, walk right and examine the Mayan Stone lying at the front of the main smouldering hut. Try and pick it up, but you'll find it's too hot. Examine the barrel just to the right, and then click on it to try and tip it over. It's too heavy, so ask Titipoco for his help. Pick the Coyote Stone up and then exit to the far left.
The Pyramid
Cut the fuel line on the left engine using the dagger in your possession. Click on the cylinder in the engine to pick it up, then use it on the fuel line to collect some petrol. Click on the fuel cap of the rightmost engine to transfer the fuel. Examine the gantry behind the engine and then pick up the rope on the floor. Get Titipoco to climb the gantry by talking to him about the rope. Grab the ends of the rope when Titipoco drops them down and attach them to the engine. Click the button on the engine to start it, and then pull the lever on the left side of the engine. Talk to Titipoco about the lever so that he can operate the machine for you, then walk onto the lift. Click on Titipoco to get him to operate the elevator.
Top of Pyramid
Pick up the ammunition belt and then get on the lift when the cursor is showing a down arrow.
The Pyramid
Walk to the guards to the left and talk to the head guard about Karzac. Walk to the right slightly so that you can see both the torch on your left and Titipoco on your right. Pick up the torch and hand it to Titipoco so that he can light it. Nico automatically sets fire to the fuel, but throw the ammunition belt onto the fire to scatter the guards. When Nico returns to the top of the Pyramid, click on the general to make him surrender. Click on George to untie him and step inside the Pyramid.
Inside the Pyramid
As Nico, click on the left lever on the wall, and then on the right lever. Talk to George to get him to help you pull both levers at the same time. All three characters drop through the floor.
Big Wheel Room
Nico must solve the Glyph Puzzle to escape, which is different each time and requires some patience. Each part of the puzzle requires three steps. Just to the right of where you begin are two huge wheels with symbols around the edge. To the right of the wheels are eight blocks set into the wall. Further to the right is a monkey statue and four more blocks. Notice that each of these blocks is a combination of two symbols shown on the group of eight blocks to the immediate left. Similarly, each of the eight blocks is a combination of two symbols from the two big wheels. To solve the puzzle, establish which two blocks combine to make the first block in the monkey statue. When you find which two symbols in the group of eight create this symbol, pick one of them. Walk to the left and rotate the wheels by clicking on them to line up two symbols in the centre so that they are touching. These two symbols will combine to make the symbol to the right. Once you have the two correct symbols on the wheel, you can walk over to the group of eight blocks and press the combined image. If you have the right wheel combination, the block depresses. Walk back to the wheels and rotate them to create the second image. Walk back to the group of eight and depress that combined image. With the correct two blocks depressed, walk to the right and depress the correct block of the four. You need to press all four blocks to escape, but from the block of eight only two blocks can be depressed at one time, so make sure you form correct sets of pairs. With the puzzle solved, an exit appears to the right. Walk through it.
