Sub Zero is a retro-futuristic puzzle adventure set in the depths of Earth’s last refuge, Triton 631, a fragile deep-sea base tasked with saving humanity. As a young boy left behind during a critical midnight mission, you awaken to find the base on the brink of collapse. Alone, with only the guidance of the base’s AI, Kibbo, you must explore its deteriorating halls, solve intricate puzzles, and uncover the secrets of Project Abyssus 2, humanity’s desperate attempt to harness geothermal energy. Navigate the haunting remnants of a dying world, piece together the story of the crew, and face choices that could mean salvation—or the end—for everyone.
