Arcbound • MVP Beta

Build the arcship. Balance the systems. Launch before reality collapses.

Arcbound is a deep, systemic sci-fi colony builder set in the final 300 days before Earth’s timeline collapses. Design and expand your Arcship from a fragile 7×7 platform in low earth orbit into a self-sustaining lifeboat, balancing oxygen, food, power, water and morale while running high-risk missions back to a dying world.
