How upgrading works (demo)
- Get the Dry Dock — fix John the Fifth’s moonshine still for the Dry Dock Key; repair the fuse box with 1 Cable, then flip the power switch.
- Research — trade Chromatic Scales to John for Scraps of Knowledge and spend research points (torn pages) in the upgrade tree. Weak Hull Protection costs 2 torn pages in the demo.
- Build the part at John’s lathe. Parts go into your storage locker.
- Install it in the Dry Dock (official screenshot above).
Fuel
- Gas stations (isolated, out on the water) and fuel cans found while exploring.
- Make your own: Grinder → Fish Meat → feed the Fuel Larva → pump with the Fuel Gun.
- Refuelling is hands-on: hold the pump for a few seconds.
- The developers call distance from safety “one of the biggest dangers” — don’t run dry far from a dock.
Damage, polyps and barnacles
- Hits from creatures damage the hull. Sea-Blight polyps and barnacles grow on it.
- Fix it in the Dry Dock: Boat Lift → Pressure Pump / Water Cannon to clear polyps → Repair Gun + Bug Slime to patch.
- Destroyed boat = you lose the hold (and reload). See surviving the night.
