"One target. A hundred masks. And something in the darkness knows their names."

A high-risk target has chosen an abandoned cathedral for their next move, hiding among the masked elite at a Halloween masquerade held within its haunted halls. Disguised among aristocrats, criminals, and diplomats, you and Ghost must infiltrate the gathering, uncover the enemy's plans, and escape before midnight. But as a storm seals the cathedral from the outside world, strange disappearances, distorted radio transmissions, and unexplained figures lurking in the shadows suggest something far older and more dangerous is stalking the guests. In a place where every face is hidden behind a mask, the line between the living and the dead begins to blur.
