Subnautica 2 adds proximity chat and revives, plus donates $100K to charity in latest early access update
Read the TDGN Briefing →Subnautica 2’s newest early access update just dropped, and it contains a bunch of co-op improvements and a very generous charitable donation.
The undersea exploration game’s Buddy System update added proximity voice chat to enhance the co-op experience, the ability to revive other players, and an option to interact with other players

Most importantly, though, the update is being celebrated by developer Unknown Worlds with a $100,000 donation to The Ocean Cleanup, a non-profit organization that helps remove plastic pollution from oceans.
“Subnautica began with a love for the ocean, and it means a great deal to continue the conservation work we started with the original game through this donation to The Ocean Cleanup,” said Fernando Melo, Executive Producer at Unknown Worlds. “We will keep doing our part to protect the ocean we have spent so long bringing to life.”
Today’s update also added a number of emotes to express yourself underwater, so if you and your friends have been waiting to dive in, then maybe this is the update to do so. Check out the full patch notes below
