The heavy blast door grinds open slowly and allows you into the deeper interior of this building. It appears to be the central hub of a shipping company's main warehouse. Crates are stacked high about the area, with numerous coordinators' kiosks suspended from the ceiling to give a full view of the area.
You press on toward the port authority then, located in the central star traffic control tower that you saw on your way down to the landing pad. You make your way there through these interconnected warehouses, each one exactly the same as the last- filled with crates, observation posts above, isles formed between the crates.

In any case, you reach the control tower. You promptly find that it is locked up tight.
