The large Harbor is a working dockyard — cranes, containers, warehouses — with one of the easiest green puzzles in the game tucked into a two-story building.
Why you’re here
A blue keycard for one fuse and a swipe, a recycler close to the water, and — since the Harbor rework — the Cargo Ship docking event, which periodically brings the ship right to the pier. Coastal bases love this monument: boat access makes the card run nearly risk-free.
The layout
Warehouses and container rows fill the yard; the puzzle building is the two-story structure — fuse box and switch inside, green reader on the second floor. Around it: barrels on the docks, crates in the warehouses, and the recycler for turning the harbor’s generous component spawns into scrap on the spot.
