What Engine Subnautica 2 Uses
Subnautica 2 is built on Unreal Engine 5. That matters because players often connect the engine question to performance, PC requirements, co-op stability, and whether older mod expectations still apply.
What It Means For Performance
The engine itself does not tell you how well your PC will run the game. Use the published PC requirements as the real buying check: CPU, GPU, RAM, DirectX 12, storage, and network conditions all matter.
What It Means For Mods
Do not assume tools made for older Subnautica versions work with Subnautica 2. Different engine, Early Access updates, and co-op architecture can all change mod compatibility.
