Rimefall is a grand strategy game set on an alien planet shrouded in permanent haze. Your colony ship has arrived, but the environment destroys electronics. Your only option: salvage the ark for resources and watch your society regress into a medieval civilization — with fragments of modern knowledge still intact.

Survive the collapse The early years are brutal. Salvage what you can from the ark. Build shelter. Grow food. Establish order. Your people still remember how things worked on Earth, but without functioning technology, that knowledge only gets you so far.

Build a nation from scratch What begins as a desperate settlement can grow into a functioning country — with an economy, trade, politics, laws, and military. A medieval society with hints of modernity: people who understand medicine but can't mass-produce it, engineers who remember blueprints they can no longer build.

Every person is simulated Your population isn't just a number. People have needs, religions, ethnicities, and opinions. Demographics shift based on your decisions. Send 2,000 men to war and watch your society change.

An economy that fights back Resources flow through interconnected systems. A wood shortage cascades into a construction halt, which cascades into housing shortages, which cascades into unrest. Plan carefully or watch everything collapse.

You play as the leader, not a god You're not the spirit of the nation — you're its ruler. Constrained by laws, politics, and what your people will accept. Want to declare war? Convince your council first.

+70 nations. One alien world. Earth's nations and corporations all sent their arks. Now they're your neighbors — and your rivals. Compete for territory across a world of black vegetation, silver sunlight, and ancient secrets waiting to be uncovered.
