Haex Review: A Wilder, Weirder Open-World Survival Adventure 2026

Haex is a wilder, weirder open-world adventure that redefines survival gaming with its procedurally generated worlds and seed-based terraforming. Set in the sub-Arctic north, you play as a research scientist exploring a rugged Scandinavian landscape where a palm-sized cube grows a plant that transforms reality itself.

What Makes Haex Unique?

Unlike traditional open-world games, Haex offers a player-shaped experience. Creative director Tobias Nyman explains that every campaign starts with a unique, procedurally generated world. Each Seed contains procedural data that terraforms the environment, creating new vegetation, topography, narrative threads, and enemies.

This means no two playthroughs are alike. The game's singularity extends to its online co-op mode, where friends can join your ever-changing adventure. The result is a survivalist experience that keeps you and your team constantly on your toes.

Gameplay and World-Building

Haex blends exploration, survival, and mystery. You'll encounter odd, shapeshifting creatures—from an ash-grey humanoid with face spikes to a sentient wall scraping the clouds. The game also introduces an unknown language of arcane sigils that must be decoded, adding a layer of intellectual challenge.

Influences include sci-fi films like Annihilation and Arrival, as well as the weird fiction of Jeff VanderMeer. The result is a hauntingly beautiful yet unforgiving world that rewards curiosity and teamwork.

Haex vs. Other Open-World Survival Games

Why Haex Stands Out

Most survival games rely on static maps or minor randomization. Haex, however, makes the world itself a character. The Seeds you plant aren't just tools—they're catalysts for change, affecting everything from the environment to enemy spawns and storylines.

This dynamic system ensures that even after dozens of hours, you'll still discover new secrets. The co-op aspect amplifies the fun, as you and your friends must adapt to a world that shifts beneath your feet.
