Subsurface is a 1–4 player online co-op underwater horror game where players dive into abandoned underwater facilities to recover valuable scrap, meet demanding quotas, and survive terrifying creatures lurking in the depths. Explore, scavenge, and escape together—but beware, not everyone makes it back to the surface.
