Communication

Add some sort of communicating between worlds with a radio when it comes out what I mean by this is that if someone is in a world and has a radio placed down in their base they can send / receive messages and screenshots like in subnautica 1 at the end when you could put out a time capsule

Something similar to time capsules would be awesome

What if, instead of a time capsule, It’s a Noa audio thing or blackbox, you can’t send supplies, but you do get to read messages from others and see a photo. That was my favorite part of time capsules anyways.
