PRIVATE ESCAPE ROOM: FOR YOU AND YOUR TEAM ONLY. 8 PERSON MAX. Approximately three days ago the U.S.S. Fortitude failed to check in at its scheduled time. What followed was a series of eerie communications from the submarine, followed by complete silence. The sub has gone dark, and the status of its crew is unknown. Your team is being sent down to investigate. Just remember: In the deep dark, no one can hear you scream.
