Wreck Recycling and Artificial Reef Restoration
I would love to see a new wreck recycling and ocean restoration system in Subnautica 2.
A dedicated vehicle equipped with robotic arms, cutting tools and a recycling module could dismantle abandoned wrecks and collect useful materials. Larger wrecks could require multiple trips and upgraded equipment.
After clearing a wreck, players could choose a predefined artificial reef blueprint suitable for the surrounding biome. Possible designs could include coral gardens, rocky mazes, underwater towers, tunnels and shelters for marine life.
Certain areas would be suitable for specific reef types depending on depth, currents, terrain and light. The PDA or player character could comment on promising locations and suggest possible constructions.
For players who enjoy building, an advanced module could allow them to design their own reef layouts by combining predefined structural elements.
Over time, fish and other creatures could begin inhabiting the new reefs. Different designs and locations could attract different species, making exploration and restoration feel rewarding.
This would give players a long-term activity beyond exploration and base building. It would also make the ocean feel more alive and give players a way to leave a positive mark on the environment.
I would love this to be an optional feature for players who enjoy exploration, engineering and environmental restoration.
