Power Source #1
Climb the ladder directly ahead, then follow the path to the right.
Jump to the scaffold and then the pipe beyond. Free run to the end of the yellow pipe section.
Jump to the scaffold through the opening in the wall.
Run over the ventilation duct to reach the elevator shaft entrance.
Free run through the elevator shaft, then climb the counterweight at the far side.
Jump from the V-shaped opening to the construction materials, then make your way through to the next room (as illustrated here).
Swing to the lower level via the pole, then run at the corrugated shutter to slide though the gap beneath it.
Climb to the very top of the crane arm via the route illustrated here, then jump to the iron girder.
Follow this rather perilous course to reach the relative safety of a suspended platform, then climb the lattice wall via the route marked by wires.
Run over to the giant spindle and slide beneath it.
Now run through the metal tube.
Follow the course illustrated here to reach the level above.
Follow the path shown here to reach the suspended girder.
When you reach the exposed upper level, climb to the top of the mechanical arm.
Make your way to the crane arm via this route.
After the brief cutscene, follow Rebecca’s prompts to jump and activate the parachute. You should then guide Desmond to the roof highlighted here.
When you return to the Grand Temple, you can insert the Power Source into a special console before you resume your Animus exploits. From your starting position, climb the crumbling staircase pictured here.
Enter the room to trigger a cutscene; when it ends, climb the staircase inside. When you reach the broken walkway, turn left and follow the route illustrated here until you trigger another cutscene. Finally, approach the console to insert the Power Source and go back to the lower level. You can now initiate optional conversations with Desmond’s companions and check his emails, if you wish, before you return to the Animus.
