One feature I would absolutely love to see in Subnautica 2 is the ability to repair and restore abandoned human bases that we discover during exploration.
Right now, finding destroyed bases and black boxes already adds a lot of mystery and atmosphere to the world. But being able to slowly rebuild some of these locations could make exploration feel even more meaningful.
Imagine finding a damaged base deep underwater with broken systems, no power, flooded rooms, and destroyed equipment. Instead of only looting it, players could gather resources to repair parts of it over time:
restoring power
fixing leaks
rebuilding rooms
reconnecting terminals
bringing abandoned bases back to life
I think this would create a really strong feeling of progression and attachment to the world. It would also fit perfectly with the survival and rebuilding themes of Subnautica.
The reason I love this idea is because Subnautica already makes players feel isolated, curious, and connected to their surroundings. Restoring abandoned structures could make the world feel even more alive and believable, especially in deeper and more dangerous areas.
Even small repair mechanics could add a lot of immersion.
Edit:
Huge thanks to thecollector877 for letting me use his restored base screenshots for this suggestion. He rebuilt an abandoned base piece by piece and it genuinely made me realize how much potential a restoration feature could have in Subnautica 2.

When I found the Alien Base Camp one, that was the first thing I thought I was going to be able to do. I thought it would be so cool to drain the water, fix leaks and restore power etc.
I agree! Even more specifically about the alien base, I really wanted to fix it and MOVE IN! It’s in such a great spot I built around it, but that feels kinda odd to have to avoid an invisible no-build zone around it…
I wanna repair it, move in, and expand it! Lemme make it mine!
If nothing else, maybe after certain main story progression within a world, allow deconstruction of explored and looted bases? They serve no real purpose after we explore them and we have a tool that should be able to reclaim that titanium! (Even if it was a reduced return amount.)
I would love this! Or at least be able to disassemble and get the resources from the old bases! So much titanium and other resources spent there that can’t be used again.
But I agree that it would be incredible to be able to get old bases going again.
I would absolutely love to repair the old bases! I love this idea
