First go up the ramp on the right hand side and climb on the block (1). Turn around, side step to the right and take a running jump to grab the opposite ledge (2). Pull up. Vault onto the ledge on the left hand side, turn around and jump up to grab the bridge above (4). Pull up.

Cross the bridge to the end and push the button to open a trapdoor behind you. Cross back the bridge and climb on the block to the left (5). Here you can see the trapdoor you just opened. Turn around and climb on the ledge above (6). Then climb on the upper one either from the left hand side where the light is or walk forwards and jump up to grab it.

Go to the end and take a diagonal standing jump to the left to grab the ladder (7). Climb to the top and crawl through the opening (8). Turn around and climb on the ledge above (stand against it and jump up to grab it - 9). Take a running jump to grab the opposite ledge (10), pull up and head to the end. Draw you pistols and shoot the electrical panel on the right hand side.

Go down and get the pick-ups and Secret as described in the walkthrough.

To get the Eye of Isis, make your way up close to the ladder. Take a running jump to grab the ledge on the opposite side (where Sophia was).

Climb up the blocks to reach the part where the artifact is. Do not attempt to step on the metal ledges or you will get toasted. Locate the button on the side of the block that is in front of the artifact. Push it to turn off the power and pick up the Eye Of Isis to end the level.
