Haex Open-World Adventure: Procedural Terraforming & Co-op Game 2026

Haex (pronounced “hex”) is a wilder, weirder open-world adventure that puts a unique terraforming cube at your fingertips in the rugged sub-Arctic north. This game blends survival, co-op multiplayer, and procedural generation into an ever-changing experience.

What Makes Haex Unique?

Players start each campaign with a procedurally generated world, and the Seed cube contains data that transforms the environment—new vegetation, topography, narrative threads, and enemies appear as you play. Creative director Tobias Nyman says, “Your adventure and your world is player-shaped.”

Online Co-op and Alien Mysteries

Haex supports online cooperative gameplay where friends join as research scientists investigating an anomaly in Scandinavia. Together, you face shapeshifting creatures like an ash-grey humanoid with face spikes or a sentient wall scraping the clouds. A layer of arcane sigils must be decoded, adding an alien language puzzle.
