    1. Retrieving Security Records

    Your first area of interest in Once Human Unfinished Expedition is situated on a ship just by the coast near the Lighthouse itself. You can reach here by sliding down from the Lighthouse. Alternatively, you can also make it to the ship by climbing the nearby tower from your location and gliding your way. Once you have reached the ship, head to the front area and start investigating. You will retrieve the Environmental Security Records here.

    2. Eliminate the Rosetta Agenta that are guarding the dock.
    3. You will see the marker on the hull of a half-sunken ship (50 meters offshore).

    5. Glide and reach the ship.
    6. You will find the Environmental Security Records on the front deck.

    2. Retrieving Medical Records

    Now, you need to head to the Hospital by following the markers and reach Rosetta Laboratory. Go to the computer to solve a rotating pieces puzzle. You need to adjust all the pieces until they form an aligned image. Doing so will grant you access to Rosetta’s medical records:
