Deep Siren is a Lovecraftian World War II horror fairytale. Alexander Calder, the lone survivor of the U.S.S. Siren, discovers a mermaid while adrift at sea and is drawn into supernatural horror far beneath the surface. Surviving terrifying creatures, navigating alien technology, and uncovering the secrets of the deep, Calder must battle to hold on to his sanity in a world where the line between the real and the unreal is constantly shifting.
