From publisher blurb:
A column of silt and bubbles suddenly erupted from the bottom of the room, followed by a bloated, green hand rising from the murk.
Explore the Flooded Room, if you dare, and discover what lurks amid the murk, muck and rubble. Will you discover treasure, a monster or something else? You’ll find out when you draw a card from the Flooded Room deck. Universal Adventures Flooded Room is a bonus expansion for the Universal Adventures Adventure Module #5 Dark Water Doom, but can be used with almost any submerged, or partially submerged, area. The set includes 9 cards which determine what happens when a character searches the Flooded Room.
