Too Many Divers - Beyond 4 Player Co-op Unlocker

Too Many Divers — Beyond 4 Player Co-op Unlocker  

🎉 VERSION 1.2.0 — NOW STABLE

The experimental version has been tested and is now the default release.

Confirmed stable with up to 16 players — host-only confirmed ✅

[line]

✅ STABLE — Confirmed working up to 16 players. Host-only confirmed clients don't need the mod installed.

Cross-platform compatibility is maintained.

Since Subnautica 2 uses P2P networking, the host handles all connections. I recommend the host to have a good internet connection and a powerful CPU, especially beyond 8 players.

💙 Special Thanks

Gin & his friends -- For being the very first to test the mod before it was even released, and potentially hosting the first ever Subnautica 2 lobby to break the 4-player barrier. That was incredibly fast XD (^o^)/

And to everyone who reported bugs, tested sessions and sent feedback this mod wouldn't be where it is without you! 🌺

❓ FAQ

Q: Does everyone need to install the mod?

A: No only the host needs it confirmed by the community! But if you want to play full safety everyone can install it.

Q: How do I know if the mod is working?

A: Host a multiplayer session → open the Escape menu → Friends List. The limit should now show 16 instead of 4.

Q: Is it safe in solo?

A: Yes the mod only affects multiplayer session limits and has no impact on solo play.

Q: Why do disconnects happen with many players?

A: Subnautica 2 uses P2P networking. High player counts put strain on the host's CPU and connection. This is a game engine limitation, not a mod bug.

Q: Can I remove the mod mid-playthrough?

A: Yes delete the TooManyDivers folder. No game files are modified.

Q: Does the mod send any data externally?

A: No. No telemetry, no external calls. Fully client-side and open source.

Q: Could not find the UE version?

A: Add this to your UE4SS config file:

[EngineVersionOverride]

MajorVersion=5

MinorVersion=4

Q: The limit still shows 4 after installation?

A: Almost always a folder structure issue check the Common Installation Mistakes section above!

Q: I can hear a strange noise getting louder and louder?

A: That's also not a mod issue. I recommend swimming faster. (^o^)/

Q: Is this mod dangerous?

A: Warning: Increased diver count detected. Recommend caution.
