Shoot out the center pane of glass in the west window and crawl through to the other side. Jump up and through the purple portal straight ahead. At the top, find the hole in the ground near the path and follow it underground. Inside, find the crossbow in a dark corner (NOTE: if you don’t have this from level 10, make sure you get it now as you will need it to finish the level).
Place Lara in front of the opening over the ramp, so that she is lined up with the rope below. Select pistols, then re-holster them. Slide, jump and grab the rope. Swing and grab the second rope ahead. Directly in front and up, notice the pane of glass which is thinner than the rest. Swing high and jump toward the glass. Draw the pistols and shoot the glass the moment you let go of the rope. Lara should land safely inside the alcove.
Find the two switches and pull them to open a door at the back of the corridor. You must draw both ALIENS into the room with the receptacles before destroying them with explosive ammo (otherwise, you will get a nasty surprise). Place the two GOLDEN SERPENTS into the receptacles to open the other door out in the corridor. Slide down the ramp.
Large Room with Waterfalls
At the juncture, go right (you will use the other path later to exit this area). Inside, pay close attention to the flyby. Kill the BIRDMAN and get the revolver ammo he drops. High above are two bridges, one leading north and the other east. Above a door at the end of each is a fuse box. Use the laser sight with arrows or revolver to destroy both. This lowers a cage in the floor at the back of the room (east end). Push the button there. The cut scene that follows shows where you began the level. Use the other corridor below the ramp to make your way back to that area.
Near the room where you started, jump through the other purple portal and head through the door at the top to find yourself on the bridge above the waterfall room. Inside the main structure, take note of the two receptacles on the wall. Go out on the other bridge and jump to the ledge that circles the main structure. Shimmy left around the corner and continue until Lara can pull up on a flat spot. To get Secret #1, continue to shimmy around to the rock bridge and past the waterfall to a flat spot. Pick up the Secret, then return to the flat spot next to the central structure.
Make a long running jump and grab the ledge on the opposite wall. Look up to find another circuit box in a recess on the ceiling. Shoot it to drop a rope nearby. Use the rope to swing and grab the upper ladder on the broken column. Climb up into a duct above. Explore the network of ducts for a couple pickups, but most importantly, make sure you find the KHEPRI’S GUARDS GEM. Once you have it, find another opening with a ladder and climb down. Slide down the ramp.
Lara is now in a corridor between a closed door, a barred door and a glass wall. Begin by shooting the glass wall. Inside, walk through the blue portal straight ahead to trigger two of the bars in the room to open. Destroy the MUTANT CROCS that barrel out (IMPORTANT: DO NOT USE EXPLOSIVE AMMO HERE AS IT MAY CAUSE A BUG LATER).. In one room is a pickup, in the other room use the crowbar to pry the IRIS OF NEKHBET off the wall.
Head back into the corridor and shoot the circuit box next to the door to open it. Around the corner is a switch to open the bars back in the other corridor. This is a timed run. Once inside the next room, make your way up the slope, avoiding the SPIKE TRAPS, BOULDER, and LASER TRAPS. At the top, activate the switch to open the door and jump on in.
Inside the next large room, kill the two DEMIGODS first (one on each side). One of them drops NEKHBET’S GUARDS GEM. Be sure to pick it up. At the north end of the room is a stone structure with hieroglyphs. On one side of it is a door. On the other side is the switch to open the door. This is timed, so quickly make your way around two the other side of the room and through the door, crossing over two LASER TRAPS along the way.
Once past the door, jump to the ledge ahead and collect the IRIS OF KHEPRI. Drop through the hole. Once again, make your way back past the room where the level started and onto the bridge above the waterfall room. Inside the central structure, combine both GEMS with the IRISES to form the EYE OF KHEPRI and the EYE OF NEKHBET. Place the artifacts in the receptacles on the wall. Look below you to see the dais below has risen to reveal a water opening. Make your way back to the lower level and go for a swim.
Swim into the underwater cavern and find the opening in the ceiling (Lara can get some air here). Pick up the SEARCH FOR APOPHIS and examine it (select “Examine” in your inventory). Swim back down and around toward the southeast corner of the room and through a narrow opening in the rocks. Pull the underwater lever inside to open a hatch nearby. Swim back into the main cavern and through the channel to the south to find the open hatch.
Room with Burning Pedestal
As you approach the bars, they will open and a MUTANT CROC will attack Lara (IMPORTANT: DO NOT USE EXPLOSIVE AMMO TO KILL THE CROC AS IT MAY INTERFERE WITH A TRIGGER).Head out and around to the room in the NE corner and push the floor switch to lower the cage around the burning pedestal. To put out the flame, shoot the water sprinkler above the pedestal with and explosive arrow (if you’ve run out, you can find some in the room nearby). Take the ENERGY CRYSTALS from the pedestal. The door at the end of the east bridge is now open, so make your way back up and head through the open door.
As you explore this area, a BIRDMAN will attack. Kill it and pick up the EYE OF NEKHBET that it drops. Slide down the short ramp and kill another BIRDMAN. Note the closed door. Jump and grab the ledge near the ramp. Follow the corridor to the end and push the button to open the door below. Back below, climb on to the ladder to the right of the open door. Shimmy left around the corner and continue until you reach the wall. Position Lara so her feet are two rungs above the bottom of the ladder. Back flip, slide, jump and grab the ladder opposite. Shimmy right, around the corner and drop. Go through the crawlspace and into the strange looking room ahead and ride an elevator up to find yourself in one of the control rooms.
Pull the lever to create an opening in the wall. This also make another opening nearby. Head out of the room and back toward the ramp. Outside, make a rather tricky running jump to grab the window ledge of the control room you just left and shimmy over to flat ground. Follow the corridor into the NW corner of the room to find the opening by the dead end. To open the door inside, you will need to find the other EYE OF KHEPRI. Shoot the window of the control room opposite the closed door and climb in. Mind the LASER TRAP inside. Jump to the other end of the room and climb onto the control console. From here, make a running jump and grab to the pillar in the center.
Climb into the circuitry duct overhead and crawl through the ducts until you find another opening. Drop and grab the ledge, shimmy left around the coroner, and pull up into the next duct. Find the next opening and drop into the control room below. Grab the EYE OF KHEPRI exit via the ducts. Back at the closed door, use the two
Artifacts to open it.
Inside, there is a closed door to the right and some bars to the left. At the other end of the corridor is a room with a lever outside. Begin by luring the ALIEN into the room at the end of the corridor (blowing the critter up will have less than satisfactory results right now). Pull the lever outside to trap it there and also raise the bars at the other end of the corridor. As you walk back notice the other two openings to the right.- one narrow and one wide.
In the room below are 4 boulder ramps. At the end of each ramp is a door and a grate. In this timed sequence, you must shoot a circuit box behind each of the four doors to drop the grate. If the boulder gets past the grate and through the door, it activates a LASER FLOOR and Lara dies. This is a good place to save your game.
Attach the laser sight to the revolver (yes, exploding arrows would be easier, but they set off the LASER floor too) and have the weapon ready. Slide down the short slope into the first opening (the one near the door where you enter this area). Quickly shoot the circuit box in the alcove at the bottom of the first ramp. Jump back up to the corridor and sprint to the other end (last opening), slide down and shoot the target. Jump back up and run to the middle (wide) opening and slide down to the platform. Shoot the box in the left alcove first, then quickly target the one in the right alcove.
If you are successful, the closed door near the start of the corridor is open. Now, release your grumpy friend from his cell and lure him into the room inside the newly opened door. Once the ALIEN is inside the room, it is safe to blast it to kingdom come and take the GOLDEN SERPENT it drops. Use the Artifact in the nearby receptacle, then take the ENERGY CRYSTALS from the pedestal.
A rope has now dropped in the next room. From the wide opening, jump to the left ramp. Use the rope to swing to the opening in the opposite wall. At the bottom of the ramp, push the button to make an opeing in the wall to the left. A cut scene shows you where to go next. Exit the other side of the control room and go to the desert corridor outside (where you began the level). Across from the hole in the ground is an opening in the rock wall. Climb the rock pillar to the left of the hole and back flip into the opening.
Skip the entrance in the ground and climb to the opening at the left. Use the monkey bars to swing to a climbable rock. With Lara as close to the rock as she will go, let go of the monkey bars and grab the ladder. Shimmy left around the corner and climb up. Across the chasm (west) is a ledge. Make a running jump to it. Climb into the crawlspace and follow it to the end. Drop out and gap the gap below (make sure Lara’s health is fully charged since a DEMIGOD will begin blasting her as she shimmies around). Shimmy until you reach a ledge to drop to. Kill the DEMIGOD from here if you like.
Jump to the landing under the ladder and use the ladders to get up to the next landing next to the bars. Jump over and use the floor switch to raise the bars. Inside the newly opened door, climb down the ladder and approach the door ahead. The door opens and you get a preview of the nasty business ahead – pay close attention to the flyby. But first, make a detour. Climb back up the ladder and drop to the ledge below. Look down to see a water opening in the floor below. Walk off the ledge so that Lara lands n the water. Swim to the other end and collect the GOLD STAR, Secret #2. Use the ladder to return.
The aim here is to shoot the boxes that will raise the bars in front of the floor switch. You cannot use explosive arrows here because the explosion will cause the grates which Lara stands on to burst into flames. So, the revolver is the only choice. It is not necessary to shoot all the boxes, only specific ones. Read the SEARCH FOR APOPHIS (in inventory) to find out which ones to shoot.
Once the bars are raised, carefully time a run past the spikes and push the floor switch. Now climb the pole in the center of the room to the level above.
The solution is:
West wall: Snake
South Wall: Eagle
North Wall: Scarab
Push the floor switch to turn off the LASER BARRIER and head upstairs. Push the button there and watch the flyby to see what happens. Climb up through the nearby opening in the ceiling and move the blocks until you find the GOLDEN SERPENT. After placing the artifact in its receptacle and collecting the ENERGY CRYSTALS, make another visit to the room below. The SPIKES on the north landing have retracted. Jump over the short slope in the middle alcove next to the landing to find Secret #3. Climb back upstairs and exit via the hallway where you found the GOLDEN SERPENT. Make your way back outside to the room with the chasm.
From the ledge under the crawlspace, do a running jump and grasp the rocks above the monkey swing. Shimmy left and around the corner until it’s safe to drop. Make a running jump/grab to the small ledge on the other side of the chasm. Jump to the rocks under the window, slide back and grasp the edge. Shimmy right until you reach a flat spot to climb up to. Deal with the DEMIGOD, then do a running jump and grab to the red block on the other side. If you like, climb down into the chasm and explore for a nice pickup.
From the red block, jump through the nearby opening in the rock wall. Push the button in the room below, then climb out and jump over to the south. Go underground again and follow the corridor. Explore until you find the IRIS OF KHEPRI. Now follow the larger tunnel, jump the gap over the LASER TRAP and head up the ramp. When Lara reaches the brown squares, the BOULDERS will be released. Once past these, you will encounter two DEMIGODS. One of them will drop a KHEPRI’S GUARDS GEM. Combine it with the IRIS and use the EYE OF KHEPRI in the receptacle by the barred door.
Back in the control room where you began the level, the hatch in the floor is now open. Do a safety drop to the room below. On either side of the entrance which is blocked by the cage is a fuse box. Lara can target the boxes through the narrow gaps in the NE and NW corners of the room. Push the wall lever to reveal an underwater lever.
Pulling the underwater lever opens the bars to the 4 underwater doors, and also releases 3 GREAT WHITE SHARKS. Unfortunately, climbing out of the water closes the bars, so if you want the fourth Secret, you will have to swim with the SHARKS snacking on poor Lara (if not, skip to the next paragraph). Turn and swim first into the nearby door flanked by the bird symbols. Pull the underwater lever inside, then head to the west door (also between two bird images). Pull the underwater lever there. Now head for the south door (snake symbol) where a block has fallen to reveal a third lever. After pulling it, head for shore (there is nothing to do in the last underwater room).
A door has opened in the south wall. Go there and collect the ENERGY CRYSTALS (note the cut scene). Go back to the room at the north side and find another open door there. Inside, pick up Secret #4, including a second GOLD STAR.
Walk into the red light shaft in the middle of the room to be transported back up to the control room. Head back to the room with the small black pyramid and climb into the crawl space in the west wall. Head into the southern branch of the crawlspace until you reach the next room. Place the 4 ENERGY CRYSTALS in the receptacles on the pillar. Save your game here to use with Level 12. Climb into the light shaft atop the pillar.
