Atlus' peculiar puzzle-adventure-morality play Catherine is out at the end of this month, but there may still be a few of you out there a bit confused by what it's all about.

Wonder no longer, because the official demo hits the Xbox Live Marketplace and PlayStation Store today. The Xbox version is exclusive to Gold subscribers.

Catherine hits store shelves on July 26. Don't forget that if you pre-order you can get your hands on the limited-quantity soundtrack CD and art book -- see the official website for details.
