The Real Review

Subnautica 2's new co-op mode is a massive hit, with the underwater survival loop and gorgeous visuals keeping most players hooked. The big problem is performance, which is widely criticized for being buggy and unstable, especially on PC and Xbox. While the base building is fantastic and the mystery is compelling, the technical state makes it feel like a rough draft, souring the overall value for a lot of people right now.
