Keepers playing Call of Cthulhu from behind a screen are doing it all wrong. They would have a hard time weaving a story with a barrier in the way.However, screens have their uses, mainly as a quick reference for charts and as a means of hiding maps and dice rolls. The "Call of Cthulhu Keeper's Screen" does the job just fine, and organizes the charts in a logical manner. The artwork on the front is not great, and could use improvement. It can be distracting to players.The main defect of this screen is the misprint where they did not add the numbers to the "Strength vs. Resistance" chart. This is one of the most important charts in the game, and I am gobsmacked that such a major defect made it onto the market.If you are running "Call of Cthulhu," it will be useful to have a screen. Just beware of the limitations.
