Large Harbor puzzle
The same green-card puzzle as Small Harbor, split across the yard — fuse on one side, green door by the big warehouse.

Overview
Large Harbor runs the same green-card puzzle as Small Harbor, but the two halves are about 45 metres apart: the fuse box and switch in one building, the green door beside the big warehouse across the yard. Still no radiation, and still the place Cargo Ship docks.
Find the fuse building
The fuse box is in the small building on the east side of the yard, away from the big warehouse. It can be boarded up — break the wood.
Insert the fuse and flip the switch
Put your Electric Fuse in and flip the switch right beside it.
Cross to the big warehouse
Cross the yard west toward the large warehouse. Use the containers for cover — the yard is open.
Swipe green
The green-card door is beside the warehouse. Swipe your green keycard.
Take the blue card
One or two crates and a blue keycard. Recycle on the pier before you leave.
Watch the water on the way out
Cargo Ship docks at the harbours and tugboats spawn here, so the quay is an ambush line. Leave through the container stacks rather than along the open quay.
