Okay, when you click on the the puzzle, it starts spinning. Here is what you
have to do. You have to remember which squares light up at the end of each
spin, and click on them in the right order. There are a total of three spins and
it gets harder and harder each spin.
Think of the puzzle as a clock. The first square(yellow) is on the 12:00, the
green square is on 3:00, orange is on 6:00, and red square is on 9:00.
There are a total of 16 squares. Below are the listings of each spin.

To get help about what you should do next, how to get something you need, or how to move the story along, bring up the Smart Alex and click on the icon at the bottom that's three horizontal lines with question marks. This will bring up a menu with a list of questions the system has answers for. Click on the one you want to see what it has to tell you.

Your inventory, map and torch are available via the Smart Alex (a kind of PDA), accessible with a right click, or the Q key. The map is used for quick navigation between locations, though it's not always available. You can use the torch in darkened locations (of which there are many in TE: ATMA), and in the easier, Casual, game mode, pointing the torch in the general direction of an object that you can pick up results in visible sparkles above the object.

The left wheel cycles through the three colors of light coming from ONLY the statue right in front of you. You can continuously turn the wheel to cycle through the colors to get the color of light you need for that statue.

The right wheel only rotates the entire assembly and does nothing else.

You'll want to make sure you've rotated the wheel to each statue and chosen the right color for it and once they all have their proper colors, rotate the entire assemble to the proper position.

For clues on the correct light colors and correct position of the statues make sure to take a close look at the sarcophagus and the symbols on the sarcophagus.

Tex's instructions for this one are a little confusing, so let me rephrase.

Each statue is carrying a sign that tells you what element it represents. The first thing you need to do is change the light on each statue so it matches that element.

Blue for water and yellow for sun are obvious; red for earth isn't quite as obvious, but it's the only color left, so red for earth it is.

The large wheel on the right moves the statues around in a circle; the wheel on the left changes the color of the light on the statue nearest to the right wheel.

So look at the sign held by the statue hit by the light from the ceiling (it's the one closest to the door you came in by). If it matches, you're good; if it doesn't, turn the left wheel to change the light until it's right. Then turn the right wheel to move on to the next statue.

When all the statues have the right color light, continue moving the right wheel until the elements of the statues match the symbol on the central stone box. When that happens, it slides aside to reveal a hole in the floor. Jump down to move on to the next area.

This is a big area with bugs flying around and mines planted all across the
area so be extra careful. Needless to say, you die and you lose [POINTS] every
time a bug gets you, or you set off a mine. I highly encourage you to make a
spare save if you haven't done it yet.

Head to the Auxiliary Station where you will find a bug nest. Before going any
further, throw a (BUG BOMB). That will stun them, granting you passage. Walk
up a bit and you'll come to a crossway. Make a left and you'll see another
bug nest. You don't have any bombs left so avoid making contact with any bugs
that you see here. Otherwise, Game Over. On the other side of the nest is a
mech (totally functional by the way) just waiting for orders. Put the (FULLY
CHARGED MECH BATTERY) inside its leg compartment and it'll fire a missile
and grant you access to the Auxiliary Room. Well, not yet. First, we need to
extinguish the fire. Use the (FIRE EXTINGUISHER) on the fire and enter the room.

Step 1: Click LEFT to change the bottom left color.
Step 2: Click UP to move the color you just made up one row.
Step 3: Repeat Steps 1-2 until you have the color order you need. The order from top to bottom is yellow red green red red yellow.
Step 4: DON'T TOUCH LEFT OR UP AGAIN
Step 5: Click RIGHT to change the bottom right color.
Step 6: Click DOWN to move the color you just made down one row.
Step 7: Repeat Steps 5-6 until you have the colors you need. From top to bottom, you need red yellow red yellow green red.
