This is a tale of possession and survival. You play as a shell, a vessel for an ancient evil, as it takes over the body of a human. Your goal is to navigate through dark, atmospheric environments and fight your way through hordes of enemies.
Gameplay revolves around strategy and timing. As a shell, you must use your environment to your advantage, luring enemies into traps and using your abilities to take them down. You'll need to manage your health and resource points carefully, as one misstep can lead to your demise.
