IRON LUNG 👁️

You were inside a one-man submarine nicknamed the "Iron Lung." There also single porthole on the sub, a map with coordinate you can use and a small control. then, a man talked to you

???: "beginning in descent. cruising depth in roughly 40 seconds, standby. Closing porthole due to depths pressure. were losing connection, so your going alone. Out." Cut

The portholes closed. Your main objective is just to blindly move to every 8 key locations and take photos of it.
