Subnautica 2 is shaping up as one of the most wanted games of 2026, with a focus on four‑player co‑op, crossplay between Xbox and PC, and a radically expanded base‑building system that aims to outdo typical survival sandboxes rather than copy GTA 6’s urban chaos.
Right now Subnautica 2 is sitting at the very top of Steam’s global wishlist charts, with over 3.8 million wishlists, putting it ahead of many classic AAA heavyweights and making it one of the few games that can realistically stand next to GTA 6 in terms of hype for 2026. Instead of chasing open‑world crime or cinematic storytelling, the sequel doubles down on systemic survival and underwater exploration, and tries to hook players with mechanics that are more about expression and cooperation than scripted spectacle.
The biggest shift is a brand new base‑building system that throws out most of the fixed modules from the previous games and replaces them with a procedural, more “sculptural” pipeline. According to the base design lead Kiel McDonald, players are no longer locked into a rigid grid of prefabs, and can freely shape corridors, rooms and viewing areas, effectively carving their own architecture out of the ocean. Windows come in far more varied forms, surfaces can be painted in different colors, lighting can be tuned room by room and interiors can be packed with cosmetic details, turning functional habitats into personal showpieces rather than simple resource hubs.
Co‑op is another pillar: Subnautica 2 supports four‑player multiplayer with cross‑platform play between PC and Xbox, so groups can explore and build together even if they are on different devices. The studio repeatedly stresses that multiplayer is optional and solo play remains fully supported, which should calm veterans who enjoyed the isolated horror vibe of earlier entries. When you combine that flexibility with the expressive building tools, you end up with a survival game that tries to stand out through creativity and shared projects, not just progression grinds. The early access release is planned for later this year, ahead of a full 2026 launch on PC and Xbox, and if Unknown Worlds delivers on the promise of “no other survival game has offered this much freedom,” Subnautica 2 could comfortably compete for attention even in a year dominated by Rockstar’s next blockbuster.
