Luna Abyss asks a simple question. What if the moon held a secret that humanity was never meant to find, and now it is calling you deeper. This 2026 action shooter sci fi adventure horror game from Kwalee Labs and Kwalee follows a technician who answers a routine maintenance call on Luna Station. Instead of a broken pump, you find blood, silence, and a hole in reality. The latest version adds a sanity meter that warps your vision and changes the behavior of enemies when it drops too low, forcing you to manage fear as a resource.
