Inside the ventilation tunnels turn left [A]. Crawl to the end picking up the instant noodles.
Near the exit there is a staircase. Use it keeping your eye on the Dwarf-Gekko. For the first time you would spot Gekko, who is used as a surveillance camera. Stick yourself to the wall and avoiding it's search-beam - pass it by.
Carefully search the warehouses. Move to the another platform. When the patrolling Gekkos arrive - just jump over the handrail and hang yourself for a while. When the Gekko's are gone - pull yourself up and move along.
The end of the walkway is just above the gates leading to the next part of the complex. Jump down and head towards the exit, avoiding the Gekko-cameras. Watch out outside - there are two idle Gekkos [A].
Keep yourself near the left side and move forward near the wall. At some moment the Gekko would wake up and would start going in your direction. Watch out not to be trampled by it. Pick up the scattered items and enter the next area.
