Eight people is a reasonable number of players for an escape room. Everyone will find something to do: strategizing, taking charge, searching for clues, solving puzzles, cheering the team on, counting down the minutes, or chatting up the game master.

You have one hour to discover who your captors are, find a way to escape and complete your mission!
