Physics-driven underwater survival horror. Layer-based progression. This game features detailed health and radiation systems — creature damage, environmental hazards, and radiation exposure all affect your survival in different ways, so you're managing more than just a health bar. Character progression comes through upgrades granted in the ancient structures found in Layers 3 and 4. There's a vast roster of enemies, each using physics-based movement instead of scripted animation, so encounters play out differently each time. More enemies are planned for future updates. Combat is physics-based, and expands after upgrades with new weapons and dash abilities. The goal is to descend as deep as possible, and survive as long as possible.
