About B.E.L.O.W.: The Asylum, from BoardGameGeek:

A once-abandoned asylum now harbors something far worse than its crumbling walls suggest. People are vanishing, eerie chants fill the air, and strange lights flicker in the darkness. The ritual is not yet complete - there is still time to act. As elite B.E.L.O.W. agents, you are the last line of defense against the horrors that should not exist. With a Lovecraftian theme, B.E.L.O.W.: Asylum is a fully cooperative, one-shot action-horror board game that blends deep strategy with an immersive, ever-evolving narrative. Play as unique, asymmetric characters, each with distinct abilities, as you uncover the truth hidden within the asylum's haunted corridors. Face off against bizarre and lethal threats, adapt to unpredictable challenges, and master protective rituals to halt the growing evil. Players must activate 4 artifact seals around the board and finish the ritual to defeat the Monarch. With randomized board tiles, exploration cards and ritual rings, there is great replayaility. -description from publisher
