I Love my medusa, it will never leave. You want a tough game, turn on the subtraction target and try to conquer Olympus. The last ball extended play feature is cool. "Time your shot...Light Gorgons!" I have only seen one Catacomb in person, did not have a chance to play. I watched the YouTube video, seams just as challenging as Medusa. Love the multi all feature and how it works. Hope I have the chance to play one.
