Nightmares from the Deep 2: The Siren’s Call is a single-player adventure about Sarah Black, curator of the Caribbean Naval Museum. After a mysterious messenger delivers an artifact, attackers steal it and draw Sarah into a conflict tied to Kingsmouth, a forgotten fishing town. Its residents are being transformed by a curse attributed to the town’s mayor, Murray, and Davy Jones, giving the puzzle-solving journey a supernatural maritime setting.
The game mixes interactive hidden-object scenes with mahjong and other forms of gameplay, rather than relying on one puzzle format throughout. Its dark mystery also emphasizes plot twists and character, while cinematic sequences and varied locations support the story’s shifts from the museum to Kingsmouth. Collectibles add another pursuit alongside the puzzles, and hidden-object scenes and minigames can be replayed.
A bonus adventure expands the story with a separate tale about praetorians seeking redemption after decades of serving Major Murray; concept art, wallpapers, and a soundtrack are also listed as additional materials. Its blend of investigation, hidden-object challenges, and other puzzles is the defining context for understanding what kind of game those player figures describe.
