First start on Dawn Waves, then go head to the red terminal, there will be lots of stairs.

Climb up all of them until you're on top then disable the door, jump up and grab onto the vents or climb the pipe up, then go on left.

Then there will be a path going upwards. Follow that now look down, there should be a big massive light.

Jump on top of it then jump onto that massive bronze kind of thingy, then go to the edge until you're facing the yellow terminal look down.

You will see a helicopter kind of sculpture jump on the wing, then move to the right (don't fall off) then hack from there.

WALLA!
