For denizens of co-op boardgames, Scotland Yard is a name that should have crossed their path.  It is a classic game in which up to 5 co-op partners play police officers as they hunt for the mysterious Mr X around London.  The boardgame is a co-op experience for most of the players, except for Mr X who must run on his own.  The new Scotland Yard iOS for iPad and iPhone aims to remedy this and can be played pure co-op if 5 players chose to go up against the Mr X AI.
