Nitrox 1.8.1.0

In this version, we focused on the bugs that had the most impact on you, and also added a sync that was not planned before 1.9 but which was mentioned in many of your comments on 1.8: Exosuits and ore deposits. In addition, we continued to support Linux versions by stabilizing what we had done previously and adding support for Heroic Game Launcher (equivalent to Epic Games on Windows)

Thank you very much for all the feedback you gave us on last version. Unless we discover other significant bugs, this should be the last content update for 1.8. We are currently working on the next update.
Players on Epic Games, Steam and Microsoft Store can now play with Nitrox 1.8.1.0 on the latest version of (Subnautica).

The long-awaited Nitrox update is finally available to everyone, and we're aware that you've been waiting for it for over 3 years now. Although there are several reasons for this, the primary reason was the Subnautica 2.0 update, which brought huge changes to the base game, causing a lot of issues on several important systems required for Nitrox to work.

With a few months of work, we were able to get something running, even before that update was released to the general public. But in hindsight, we weren't at all comfortable with releasing an update in that state. So we decided to rewrite most of the mod from scratch.
This was done both to allow us to detach ourselves from the workarounds we'd used over the thousands of updates the game had undergone since its early access, but also to clean up all the mod's important systems to allow us more freedom for future updates, and to make your in-game experience better.

Players on Epic Games, Steam can now play with Nitrox on the latest version of (Subnautica).

Highlights

• Subnautica 2.0 Compatibility: We've dropped support for all older versions of Subnautica, the only one supported is the final version of the game (Subnautica 2025 Patch)
• Launcher : Third time's a charm, and we're back with a brand-new responsive Launcher. This time it's been designed to be cross-platform compatible (Windows, Linux, MacOS), while improving on the functionality of the old one. It's now possible to manage multiple servers from the launcher interface, while customizing their settings and restoring backups of your worlds. This should help with corruption problems should they arise.
• Entity system : The way Nitrox interacts with objects and instances of all kinds has drastically changed to become a unified Entity model. With the new entity system, the way entities spawn had to change to fit the asynchronous Subnautica spawning model. For example, lifepods, wrecks, fragments should no longer be missing so regularly.
  It should be way faster and more stable now, and will allow us to easily add more sync to game behaviors with minimal bugs.
• Building : The legacy Nitrox building system was put in place years ago when Subnautica was first released. Thus it would forcefully become outdated with Subnautica updates over the years. It was finally the opportunity to rebuild it from the ground up, to make a brand new building system, more reliable, robust, adaptive, and relevant to the base game. For old players, it'll finally be a great relief to be able to build full bases with no fear of losing all progress because one piece was built in a wrong way. For new players, it's an opportunity to discover the new base pieces from Subnautica v2.0 in multiplayer.
• Story : The story sync and persistence department was pretty flawed, which we realized while trying to fix it. We've tried to focus on the major issues players can encounter while trying to play Nitrox: the radio, the lifepod signals, the sunbeam, and all the gameplay linked to the Aurora. In that regard, we've added a lot of extra synchronization, to make progress on Nitrox less annoying (i.e. Cyclops, Radiation, Leak, ...)
• Vehicle movement : For various reasons, syncing movement in multiplayer video games has always been a very tough problem which we have finally decided to solve for good. There should now be a way smoother and lighter, vehicle movement sync which adapts to the players's variable latency.
• Player movements in Cyclops : A very bad issue that was annoying all players for years was moving around in a moving Cyclops. After greatly improving Cyclops movements themselves, we decided to also vastly improve player movements in Cyclops. No more being sent to space just because another player started driving the Cyclops! (RIP Nitrox space program) You can now safely do anything and go anywhere in the Cyclops while your mates are driving really fast, even when it's upside down !
• Sound system : Nitrox's sound system has been completely overhauled for your listening pleasure. In particular, we've corrected the calculation of volume as a function of distance, and we've also corrected a few problems with the 2D sounds, which could be blocked indefinitely.
