This walkthrough is meant as a general guide only. It may not include every pickup or secret. There may also be alternative ways of approaching situations within the game.
The level begins with Lara sliding down a slope into the 1st room. On the ledge and floor are light brown/beige coloured tiles. Run over all of the light brown/beige tiles and head towards the large doors, passing over the tiles there. The large doors open but do not proceed. Instead, turn around and enter the newly opened gate at the back of the room. Enter the corridor and the gate closes behind you. Take a running jump and grab (to change trajectory) over the two spike pits in this corridor. Climb the ladder at the end of the corridor to the crawlspace at the top. Shimmy as far to the right as possible and quickly let go and grab again. Immediately shimmy to the right before Lara can position her feet on the ladder and climb into the crawlspace. Climb out of the other side and drop down into the next room. Enter the area, turn right and shoot four scorpions. Head to the corner on the right (north/west) take a standing jump over the sandhill and shoot another scorpion. Pickup the Shotgun in the corner. Turn around and take a standing jump out and head right towards the other corner in the room (south/west) and safety drop through the hole in the floor. Take a running jump and grab over the flame pit and pull up into the main room. Now head through the large doors.
Follow the corridor around and shoot three ninjas waiting in the next room. Pickup the small medipack left behind by one of them. At the end of the room in the left corner is a ladder. Approach the ladder but do not step on any of the light brown/beige tiles as this will activate spikes under the ladder. Instead jump over the tile and climb the ladder safely. Backflip into the room above and pickup the Shotgun ammo. Climb back down. Turn right, jump over the brown/beige tile and head into the corner ahead and to the left (south/west). Go through the corridor and enter this new area.
Take a standing jump to the flat surface on the left and turn right. Get ready for a series of jumps. Jump and grab the first slope. Shimmy as far to the left as possible. Pull up and jump to the next slope. Jump and turn left to reach the next slope. Jump and grab the crevice on the wall. Wait as a cutscene shows you the route. Shimmy to the right around the block onto the next slope as far as you can go. Pull up and backflip to the slope behind. Immediately jump and while in the air, turn to the right. Jump again, reverse roll and grab the pole. Shimmy around the pole and backflip onto the flat area. Turn left and drop down. Turn left again and run towards the ammo ahead but don't pick it up yet. J Jump back to avoid the spiked boulder then safely pickup the Revolver ammo. Side flip into the corner on the right and do a backflip onto the slope behind. Jump and grab the crawlspace. Pull up and pickup the Ba Cartouche. Crawl back out the way you came, turn around and head back out to the water.
Secret #1: On the left is an alcove and a lever. Take a standing jump and grab (to change trajectory) to the alcove and pull the lever. An underwater gate opens. Turn right, exit the alcove and take a standing jump into the water. Turn right and swim through the newly opened gate, which is Secret #1. Pickup Shotgun ammo and a small medipack. Exit the alcove and swim ahead. [note: swimming over the blue square triggers the closing of the underwater gate.]
Pull up onto the slope ahead and exit this area via the corridor on the right.
Head to the large hole in the middle of the room. Climb down the ladder on the west side of the hole and drop down into the room below. Drop to the lower floor, turn left and pickup some more Shotgun ammo. Turn left, climb the block and place the Ba Cartouche in the receptacle ahead. Wait as a boulder falls out of the way. Turn left and climb the block. Face the slope and do a standing jump to the tile with the Pharaoh face. Immediately side jump to the right out of the way as a boulder falls. Turn left and make your way back to the first Pharaoh tile, which is now safe. Angle left and take a standing jump to the next Pharaoh tile. Immediately side jump to the right as another boulder falls. From the top right corner of the first Pharaoh tile, take one step back, then angle to the right to face the last Pharaoh tile. Take a standing jump to the tile. Immediately jump, reverse roll and while in the air, turn right to avoid the boulder as it rolls out of the way. The gate at the top opens so make your way back to the top of the slope and enter the alcove. As the second gate opens, watch a cutscene of a boulder on the slope ahead. Walk to the edge of the pit, turn left and do a sidejump to the Pharaoh tile. Immediately angle left and so a standing jump into the alcove as the boulder rolls out of the way. Head up the slope and turn right. Before heading down the corridor, turn around and jump up and grab the ladder on the inside of the wall above. Climb to the crawlspace at the top. Shimmy as far to the right as possible and quickly let go and grab again. Immediately shimmy to the right before Lara can position her feet on the ladder and climb into the crawlspace. Pickup the small medipack and climb back down. Reverse roll and head down the corridor. Shoot the two scorpions that appear from the left and right alcoves and exit to the next area outside.
There are two ninjas outside. Shoot the one on the right and follow the other one who has headed around the pool to the left and up on a hill. Shoot him, head to where he was standing and pickup the Cartouche Piece. Head back down to the pool. Facing south, drop into the pool and dive down. There is a crawlspace about ¾ of the way down. Swim through the crawlspace. There is an air pocket up near the beginning so take a moment to fill up on air. Then swim down and make your way (south) through the crawlspace. At the end is the second Cartouche piece. Reverse roll and quickly swim back (to the air pocket alcove if necessary) north then up to exit the pool. Back at the entrance to this area is a small ladder above the door. Jump and grab the ladder, pull up into the alcove. At the end, turn right and climb into the corridor. Follow the corridor around and jump over the Pharaoh tile. (A spiked boulder will fall if you walk over the tile). Pull the lever at the end of the corridor, turn around and follow the corridor back out. When you reach the Pharaoh tile, reverse roll onto the tile so that you slightly touch the tile and immediately run out of the way as the boulder falls. Side jump over the boulder and face south where there is an alcove above. To get up into this alcove you have to position Lara as high as possible at the left end of the alcove and just press ctrl and the up arrow to initiate the jump up (ignore Alt). Pull up, combine the two cartouche pieces and place into the receptacle on the wall.
Secret #2: To get this secret, you need to shoot 5 vases in various locations. To begin, shoot the two vases in this room. Exit the room by climbing the ladder on the wall opposite the cartouche receptacle. At the end of the corridor, shoot the third vase. Take a standing jump and grab the ladder and climb down. Reverse roll and head forward. Shoot the two vases in the left and right alcoves. Head back outside and turn right. On the right is a set of stairs. Climb the blocks and follow the corridor to the end. Enter the small room and pickup the Revolver and Revolver ammo, which is Secret #2. Reverse roll, exit the small room and head back into the large building.
Turn right at the ladder where you dropped down from the Cartouche receptacle room, select the Revolver from inventory and follow the corridor. If you use the Revolver, you can take out one ninja from up above. Next, you can either jump and grab the pole and slide down or reverse roll, drop down and shoot another ninja before he gets a shot at you. Run around the room and shoot the last ninja and pickup the small medipack he leaves behind. Locate the light gray doors on the east wall and exit this room.
Follow the corridor and climb the pole. Turn and backflip into the room. Turn around and watch as two zombie mummies slowly approach. When you can, make a run for the pedestal ahead and pickup the Eye Piece. Make your way to the hole in the center of the room and climb down the ladder. On the left there is a series of fire tiles, two ropes and a lever in the corner. Turn to face the lava pool and take a running jump and grab the rope. Turn to face the corner on the right, swing and jump to land in the corner with the lever. Push the lever and face the lava pool again. Take a standing jump and grab the edge of the pool. Shimmy to the right until you reach a midpoint between fire tiles (screenshot #1). Pull up and take a standing jump out of the fire. Turn around and take another running jump and grab to the rope. This time, turn towards the second rope. Swing, jump and grab the second rope. Then swing, jump and grab the crawlspace. Pickup the Shotgun ammo on the right. Exit the crawlspace and turn left to face another rope above a water pool. Take a running jump and grab the rope. Angle to face the block on the left and swing, jump and grab the edge of the block. Pull up and turn left into the alcove. Take a running jump and grab (to change trajectory) over the well hidden spike pit and pickup the second Eye Piece. Exit the alcove and drop into the water. To get out of the water, swim to the sloped blocks. Position Lara so that she is in the middle of the sloped block on the left, pull up, jump, reverse roll and grab the rope. Angle right, swing and jump to the floor ahead. Combine the two Eye pieces and place in the wall receptacle ahead. Angle right and take a standing jump to the slope. Jump off the opposite slope and while in the air, angle left. Continue to jump back and forth, making your way over the fire tiles, over the spiked boulder and eventually you will fall through a hole into a pool of water.
Pull up onto the south/east ledge with the vase. Shoot the vase and pickup some Shotgun ammo. Jump back into the water, swim to the alcove in the north/east corner and pickup the Shotgun ammo. Swim back out and pull up onto the ledge on the right. Turn right and even though it doesn't look like it, there's a ladder in the corner. Jump up and grab the ladder and climb to the top.

Draw weapons again and dispatch the pesky little ankle biters. Go back to the north/west corner, drop down and pickup some Shotgun ammo. Climb back out and exit the crawlspace on the right.
Death by Mist: From the center when the mist stops, drop into the pit and pickup the large medipack. Immediately grab the block ahead, shimmy to the right and pull up into the crawlspace. Turn around and when the mist stops, exit the crawlspace. Immediately turn left, jump up and grab the block and pull up. Go as far as possible and turn right. When mist stops, pull up into next alcove. Immediately turn right and angle to face the next alcove and do a standing jump and grab to it. When the mist subsides, pull up and immediately turn around.
