(Note: Those who have played and completed the original Tomb Raider should recognize the level as Atlantis. However, Crystal Dynamics have merged Atlantis and The Great Pyramid into one level. You will recognize the latter when you reach the end of the level.)

[Checkpoint] Room with six cocoons - The level begins where the previous one left you. Slide down the slope and go through the door you opened. Follow the passage and pick up the Mini SMGs Ammo. The end takes you to a room with six cocoons; three on each side. There is also a closed door in the back left corner that will open later. Go to the other side of the room and pick up the two Mini SMGs Ammo's from the right (or wait until you get them after the battle that follows). Go through the next opening.

The cut scene shows Lara entering the next room. There is lava at the bottom which means she cannot go down. She takes a look above and notices that this is a really tall room. At the top, Natla is standing on a ledge, holding the Scion. She then goes inside a room and we see a kind of electricity. The room starts shaking and the camera shows the outside area. The rocks at the top of the mountain shatter and a pyramid is revealed. Back inside, Lara retutns to the previous room. One of the cocoons explodes and a flying mutatnt is getting released.

After the cut scene, four mutants have been released and one of them is flying. Draw weapons and kill them. Go towards the entrance of this room (the door is now closed) and notice that the door at the far right (as you return) is now open. Go through it and climb up the ladder. Turn around and enter the room above the six cocoons. Two of them will explode and two flying mutatnts will get released. Quickly draw weapons and kill them. Pick up the Mini SMGs Ammo and two Large Medipacks. Go through the opening at the far left and follow the passage to the next area.

Tall room/ Going up - You reach a ledge in the tall room you saw before, but this time a little bit higher. You have to reach the top of the room, but this procedure can be proved frustrating, so be patient. Pick up the the Large Medipack and Mini SMGs and Shotgun Ammo from the left. Notice the button on the right hand wall. Draw weapons and shoot it many times until all symbols around it glow. This will bring up a ring above the button which will stay there for about 11 seconds and extend a ledge that is higher at the other side. It will also release a flying mutant and by the time you have killed it, the ring will have slid inside the wall. Shoot the button again, jump to grab the crevice in the pillar and traverse around. Jump to grab with your Grapple the ring and perform the wall run to reach the handhold in the opposite corner. Jump to grab the crevice in the pillar above, traverse around and jump to grab the ledge behind you; pull up. [Checkpoint]

Second ledge - Shoot the next button until all symbols around it glow. Again, it will bring up a ring above the button which will stay there for about 15 seconds and extend a ledge that is higher at the other side. A flying mutant will get released and this time the ledge you are standing on will start sliding into the wall. Kill the mutant and shoot the button again. Jump to grab the crevice in the pillar, then the next one. Traverse around and jump to grab with your Grapple the ring above the button. Perform the wall run and jump to grab the crevice of the pillar in the opposite corner. Jump to grab the upper crevice and traverse around. Jump to grab the next crevice above, then the ledge behind you; pull up. [Checkpoint]

Third ledge - Shoot the third button until all symbols around it glow. This time, it will bring up two rings; one above the button and another one on the opposite wall. It will also extend three horizontal poles; two on your side and one on the wall with the button. Before doing anything, kill the two flying mutatnts that get released. You have about 18 seconds to make it to to the next safe ledge, before everything slides back into the wall. You have to jump on the slope of the pillar, jump to grab the first pole, then the next one. Turn around, swing and jump to grab the crevice in the pillar (above the slope). Traverse around, jump to grab the pole, immediately jump to grab with your Grapple the ring above the button and jump to the slope in the opposite corner. Before sliding down, jump to grab the next ring and perform the wall run to reach the crevice in the next pillar. (The procedure is shown in two screenshots: first and second.) Jump to grab the crevice above, traverse around and jump to grab the ledge behind you; pull up. [Checkpoint]

(Note: If this procedure becomes really frustrating and you keep falling to your death, you can ignore the horizontal poles and jump directly to grab with your Grapple the first ring. To make sure Lara will catch the ring, press and hold the Jump button to jump higher and further. Once there, you have to climb up the Grapple line a bit, then perform the wall run. The procedure is shown in this video.)

Fourth ledge - Shoot the fourth button until all symbols around it glow. It will extend two horizontal poles and a slope from the next wall which will stay there for about 9 seconds. Again, two flying muntants will get released, so kill them before doing anything else. Shoot the button to extend everything and jump to the slope in the corner. Jump to grab the first pole, swing and jump to the extended slope. Jump to grab the next pole, swing and jump to grab the crevive of the pillar in the next corner. Jump to grab the upper crevice and traverse around. Jump to grab the ledge behind you and pull up. [Checkpoint]

Fifth ledge - Shoot the fifth button until all symbols around it glow. It will extend two rings; one on the wall with the button and one on the opposite wall. Both will stay there for about 15 seconds, but before doing anything else, kill yet another time the two flying mutants that get released. Shoot the button again and jump to the slope in the corner. Jump and grab with your Grapple the first ring, perform the wall run and jump to the slope in the next corner. Jump off the slope and grab with your Grapple the next ring. Perform the wall run to reach the crevice of the pillar in the left hand corner. Jump to grab the upper crevice and traverse around. Jump to grab the ledge behind you and pull up. [Checkpoint] Pick up the Large Medipack and Caliber Pistol Ammo.

Artifact - Before going through the opening, notice the alcove at the other side (if the opening is on your right). Jump to grab the crevice in the pillar, traverse around and pull into the alcove. Pick up the Artifact and jump to grab the edge of the ledge you came from. Pull up and draw your weapons. The last flying mutant of this room has been released, so kill it.

Passage with traps - The passage gets you to a series of traps. First, pick up the two Shotgun Ammo's from the left. When the triple closing door has opened, run past it. Approach the fire shots and wait until they stop. Pick up the Large Medipack and run back. When the fire shots stop, run and stop just before the triple closing door. Pass it when it opens and proceed to the next trap. Again, run when the fire shots stop and stay just before the triple closing door. Run past it when it opens. Follow the passage to the next room. [Checkpoint]

Lara's mirrored creature - Before sliding into the room below, take a look at the opposite side to spot something that moves when you move. Be careful not to accidentally shoot it in the next battle. Slide into the room with your weapons drawn. Three mutants will attack, so kill them. Approach the middle of the room and examine the creature. It does exactly what Lara does and it can even shoot you if you shoot at it, which means that if it dies, you also die. To leave this room, you have to kill it. But instead of shooting it, you have to lure it into a trap.

First, pick up the two Mini SMGs Ammo's from the back right and far left corners of the room. The creture's side, where it will be trapped, is the one you came from (with the exit door above - see this screenshot to get oriented). Your side is the other one. Rotate the mechanism to extend two ledges; one beneath each ladder. They are timed, so run and jump to grab the ledge on the right (assuming the entrance is to your back). Pull up and climb up the ladder. Jump to grab the crevice on the right and, before the steam of the crevice pushes you back, jump to the ledge behind. You will land on a trapdoor which will close the exit door. Pick up the Large Medipack and draw weapons. As you proceed further, a flying mutant will be released from the cocoon, so kill it. Pick up the Caliber Pistol Ammo and use the switch to open the trapdoor you landed on before. The trapdoor is timed and you have 30 seconds to lure the creature here and kill it.

So, jump down and rotate the mechanism to extend the ledges. Run and jump to grab the ledge on the left (if the entrance is to your back). Pull up and climb up the ladder. Jump to grab the crevice on the right and jump to the ledge behind you to land on a pressure plate.

If you make it on time, the cut scene will show the last part of your jump. Lara jumps on the pressure plate and since the creture follows your moves, it will jump back too, but it will fall through the trapdoor and into the lava. The creture will die and Lara will comment "Talk about being your own worst enemy".

Pick up the Large Medipack and draw weapons. A flying mutant will be released from the cocoon, so kill it. Pick up the Shotgun Ammo and use the switch to open the exit door. Drop down and rotate the mechanism to extend the ledges. Climb on the one that will lead you to the exit (the right one if the entrance is to your back) and climb up the ladder. Jump to grab the crevice on the right and then jump to land on the trapdoor behind you. Since the creature is dead, the door will not close, so go through it. [Checkpoint]

Room with lava pit and two trines of metal cylinders - Follow the passage to the next room. Be careful not to accidentally fall into the lava pit ahead! There are two switches in the room and to reach them, you have to pass above the two moving trines of metal cylinders. To pass them, approach the wall and turn to face each trine. Press the up cursor key and start tapping the Jump button. The right hand switch opens the door opposite the entrance and the left switch extends a ladder so you can reach the door. You will also find a Large Medipack close to the right hand switch. Every time you use a switch, a flying mutant attacks, so kill both.

Relic - Cross the bridge, but do not go through the door. Draw weapons and shoot the rock above (as shown in this screenshot). It will fall down, destroying a part of the floor. Drop to the slide below and jump to grab with your Grabble the ring beneath the bridge. Swing to the alcove ahead and pick up the Large Medipack. Continue through the passage and climb up the ladder. Pick up the Torc of Embitterment, climb into the opening and drop down at the other side.

Cross the bridge and jump to the opposite side to end the level.
