A first-person survival horror game set on a mysterious island. Explore, survive, and uncover the anomaly twisting its very essence as creatures hunt, environments shift, and danger rises with every step.
Anomaly Island
SteamAnomaly Island is a first-person psychological horror game set on a seemingly peaceful island hiding something ancient, corrupt, and alive. What begins as calm exploration slowly twists into a descent through shifting biomes, strange creatures, fractured realities, and an anomaly that watches your every move.
You start your journey in a quiet cabin surrounded by nature. The wind is soft. The world feels calm. But the longer you stay… the more the island changes.
Explore dense forests, corrupted zones, abandoned structures, and places where the laws of nature no longer apply. Face spider-like creatures, environmental dangers, and unpredictable anomalies that distort vision, sound, and space. Manage scarce resources, navigate traps, survive hostile biomes, and uncover the story behind the island’s decay.
The island is alive. And it remembers every step you take.
