Go through the next crawlspace and drop down into a hallway with a lantern. Continue in either direction to reach the main hall - a large room with a balcony and several blue double doors on both levels. Go to the first door on the left and press [action] to push it open. Go through the hallway and break the jar to get the small medikit and Uzi clips inside. Continue to a room with banners hanging from the ceiling and a golden circle inscribed on the floor.

Two mechanical men emerge from the alcoves. These guys are difficult to defeat since their only weak spot is the blue gem on their chest (you'll hear them grunt when you hit it). They let out a moan as they keel over and die, but don't waste ammo on them - just use your pistols and move around a lot.

There is a scroll on the pedestal here, but you can't pick it up yet. It will be possible to get it later in the game and it's known as the fire circle scroll. When examined, it reads: For the serpents to live,all must first be stilled. Provoke each in turn, and the circle will burn complete. Return to the main hall the way you came.

Go to the second door on the left when facing the big double doors and press [action] to push it open. Go through to the hole and look down. Jump to grab the climbing pole and quickly slide all the way down to the bottom with your eyes shut. You can patch yourself up with a medikit when it's safe if you need to!

Follow the hallway to the second pole. There's no need to climb it. Just stand below one corner of the opening, wait for the blade to pass to the other side, then pull up through the opening and run around to the steps that exit the room. In the next room. kill the mechanical man and use the crowbar to pry the golden star out of the column. Go to the rear of the gear on the right (when facing the two gears) and turn Lara so her back is toward the edge of the turning gear. Drop back, grab the edge and climb down the ladder etched into the wall. Safety drop into the pit to find Secret #1 - a small medikit, revolver ammo and Uzi clips. Climb back out the way you came.

Go along the side of the room and climb the ladder on the side of the tall structure in the middle. Go through the door on the T-shaped platform above to an opening with a climbing pole. Slide down the pole. In the room beyond, two mechanical men emerge as you explore. Destroy them and take note of the locked gate with the receptacle next to it. You'll need to find something to put there. Enter the next room and climb down the ladder. Go through the crawlspace and enter the room beyond.

A mechanical man runs into the room, mounts the bronze horse and begins riding around the room. He is very hard to kill but fortunately he won't do much damage as long as you move around a lot to stay clear of his axe and the horse's hooves. After you've shot him in the blue gem for a while, he'll get off the horse and come after Lara on foot. Keep firing and he'll eventually fall. Take the horseman's gem that he drops.

In the room to the south of the main room, there's a gate with a pulley mechanism hidden behind a stone overhang in the roof. Use the laser sight equipped crossbow with normal arrows to target the dangling ball. When you hit it, the gate opens. Climb in to get Secret #2 - a large medikit, shotgun shells and Uzi clips.

Return to the main room and exit through the door where you entered. Go through the crawlspace and climb the ladder back to the room with brass arches and pipes. Use the horseman's gem in the receptacle near the small gate to open it. Enter and pull the chain. This raises a gate in an underwater room below. (You can see this area through the grate in the floor.). Exit the alcove and make a U-turn to the right to return to the climbing pole. Climb up, back flip to the floor and go up the steps to the upper level of the room with hug gears. Go to the right along the T-shaped ledge and climb back down the ladder to the floor.

Cross the room to the side opposite the gears. Go through either door. The rooms beyond have swinging chains. You can easily avoid these by crawling down the side of the passage or by running carefully past them. When you reach the room with the single turning gear, stand at the edge of the metal trapdoor in the floor, facing the low ramp and press [action] to open it.

Jump into the water and swim through the short passage into the large underwater room. Cross this and swim through the gate opposite (now open if you pulled the chain in the room with brass arches above). Exit the water and use the crowbar to pry 2 golden stars from the wall. Swim back the way you cam and climb out through the trapdoor. Return to the room with huge gears past the swinging chains and go through the door where you entered this room.

Drop down into the hole at the base of the pole when the blade moves to the other side. Follow the hall to the other pole. Climb the pole as quickly as you can to get past the first blade. Back flip to land on the ledge and shoot the jars to get a large medikit and shotgun shells. Take a standing jump to grab the pole. Slide down a little to avoid the second blade, then repeat the steps above to get to the next ledge. Shoot the jar for a small medikit and then jump for the pole again.

When climbing up through the last blade, position Lara so there's no wall behind her on the upper level (look up through the hole to check). Wait until the blade begins to move toward the opposite side of the opening, then jump to grab the pole and immediately back flip onto the ledge above.

Continue on to the main hall, cross the floor and push open the door on the far left (to the right of the big double doors. Shoot the jar in the hallway to get a (difficult to see) small medikit. Follow the hall to a big room with celestial atterns on the ceiling - the Planetarium. Slide the globe with the blue band around the middle onto the thick, gold circle at the center of the floor diagram. A glowing white orb appears above the globe, showing that it's in the correct position.

Use the three golden stars you collected in the previous area in the small receptacles near the closed gates. The gates will open in turn to reveal more globes. Now you need to move the globes onto the correct circles within the diagram: white - inner circle; green - second circle; pink - third circle; yellow - outer circle. When all of the globes are positioned properly, blue lightning crackles between the globes and the gold circle on the north wall, and a door opens below the gold circle.

Go through the door and continue, shooting the jar at the bend in the hallway to get a large medikit. At the next bend, shoot the jar to get a box of wideshot shells. Now push open the blue double doors, which should be just to the left of where the jar stood - these lead back to the main hall and you should enter the hall, cross over to the other side and push open the middle doors on the other side of the room. Now cross back to the door you came from (to the left of the huge double doors) and continue straight on down the hall.

The next large room has a seven pointed star inscribed on the floor and a serpent statue fitted with a lever at each point of the star. This is the Fire Circle Room and you may like to go back a few stages and pick up the Fire Circle Scroll that you couldn't manage to do earlier: To get there, retrace your steps to the main hall and turn right. Go through the second door on the right and pick up the scroll on the pedestal. Now return to the Fire Circle Room.

To solve the fire circle puzzle, note that pulling any lever affects the burner on that lever, as well as the two other burners at the connected points of the star. If a burner is off, the lever will turn it on and vice-versa. Begin at the serpent lever nearest the entrance and go around the circle anti clockwise, pulling each lever in turn. You will need to go slightly more than once around the circle but once all the burners are lit blocks will rise from the floor in the middle of the room. If you make a mistake, walk over to the low platform with the star on it at the base of one wall and stand on it to extinguish all the burners.

In the PlayStation version, solving the puzzle triggers the appearance of a fire elemental. You'll need to find some water quickly to extinguish it. Run towards the blocks in the middle of the room and climb up them. Jump for the hole in the ceiling and haul yourself up through it. Run up the stairs and jump into the pool below the fountain to wait for the elemental to extinguish itself. PC players can take a more leisurely stroll along to the same point!

Go past the fountain to a room with scrolls scattered around the floor and a ladder leading to the upper level. Climb the ladder, go around the balcony and shoot both jars to get a small medikit from the second one. Climb back down the ladder. Follow the hall to a room with benches and scrolls, breaking the jar in the hall on the way to get some Uzi clips. Go down the stairs and push open the blue doors to emerge on the balcony of the main hall. Turn right and cross the balcony to the other side.

Open all the doors along this wall now to save time and then go through the rightmost door of the three. Slide down the ramp but around two thirds of the way down jump and grab the ladder carved into the wall of an opening above Lara's head. Climb up to the top of a golden ledge. The ground shakes as a huge (unseen) metal globe rolls down from a chute on the other side of the room. Take a running jump from the top of the ledge to the long ledge on the right wall. This is secret #3 - a large medikit and arrows. From the ledge you can see that you were previously on top of one of several huge lion heads that adorn the walls of this room. Safety drop to the ground.

You should now be able to see the blue metal ball that rolled down the ramp earlier. When you explore near this ball, jumping over it and climbing out the other side, a mechanical man approaches from the right wall of the room. Bounce around the room to kill him with pistols. You may triger a second metal sphere to roll down the ramp during the fight - if not, walk up the ramp and take a standing jump to land on the higher part that's too steep to climb. Jump to the side to avoid it.

Go up the ramp again as far as you can. Take a standing jump to grab the switch high on the wall to the left of the ramp. This raises large stone blocks near the middle of the room. Climb to the top of the blocks and take a running jump to grab the ledge ahead. Pull up and find the opening in the wall at the left side of the ledge. Pull up into this and follow the hall around to an opening facing the side of the second lion's head. Take a running jump from the right side of the opening to the top of the head. Pull the chain. This widens the opening in the lion's mouth so you can crawl through.

Slide down the front of the lion's nose facing uphill so you can grab the edge as you slide. Let go and immediately grab again to catch onto the lower jaw. Crawl into the open mouth. If you fall, you can climb up the blocks and jump to grab the nose without having to go all the way to the top of the head again.

Climb the pole at the back of the lion's mouth to the small room above and back flip to the floor. The two gates open automatically as you approach. Go through the gate on the right to a room with many hanging flags. Enter the room and take the Pharos Pillar from the pedestal. Stand facing the trapdoor in the floor next to the pedestal, with the pedestal ahead on Lara's right, and press [action] to open the trapdoor. Note the ladder on the left side of the trapdoor leading down to the room below. Enter the hallway opposite the pedestal to draw out a fire elemental.

Run back to the trapdoor, drop back to grab the ladder and climb down. Once at the bottom of the ladder, roll and run through either door out of this room. Follow the hallway to a room with benches and a small pool. Jump into the pool and wait there for the fire elemental to extinguish itself in the water. Climb out of the pool. Check out the nearby tile with the gold orbital patterns, When standing on it, Lara looks intently at the chute high on the wall. If you select the binoculars and look into the opening, pressing [action] to activate the light, you'll see the solution to the puzzle in the Planetarium.

Retrace your steps to the room with the ladder, shotting the vase where the corridor turns to pick up a small medikit on the way. Entering the stairway to the right of the ladder causes 2 more fire elementals to emerge from the lamp in the ladder room. Lure them back to the pool to destroy them. Return to the base of the ladder and climb back up it to the room where you got the Pharos Pillar. Go through the open gate back to the small room with the pole. Go through the gate on the right.

A little way down the hall is an alcove. Pick up the wooden torch from the floor in the entrance. Step on either round grate inside the room to light one of the burners. Carefully approach the burner with torch in hand. Press [action] to light the torch on the burner. Continue down the hallway to a room with a wooden floor. Press the [draw weapons] key to toss the torch onto the wooden floor and watch it burn away. If the torch slides off the wooden area of the floor, pick it up and try tossing it again.

Drop down through the opening in the floor and pick up the Music Scroll from the floor - it's the one in the circle on the floor that Lara stares at when you walk past it. Shoot the jar to get some shotgun shells. Climb through the high doorway, follow the hall and push open the blue doors to emerge back at the main hall.

If you've already opened the doors on the, upper level, go through the middle door on this side, which leads downstairs to the room below the room where you got the Pharos Pillar. Climb the ladder to the Pharos Pillar room, go through the hallway opposite the pedestal and exit through the blue doors to emerge back on the main hall balcony.

If you haven't opened the upper level doors, go through the right door on the north side, lower level of the main hall. This leads to the Fire Circle Room. Climb the blocks, go through the opening in the ceiling, follow the hallway through the Library, through the next room, and finally through the blue doors to emerge back at the main hall balcony.

Run around the balcony and go through the door on the right. Follow the corridor, breaking a jar along the way to pick up some Uzi clips. In the room beyond, face the music stand near the harp and press [action] twice to place the Music Scroll on the stand. Lara plays a tune on the harp (sort of - she obviously bunked off music lessons at finishing school!) and a nearby door opens.
