It's chaos on the (purple) high seas! Pirates are parachuting out of the sky and you've got shoot body-doubles of each pirate from your cannon. This implausible  scenario (as is so often the case) sets things up for a fun game. Essentially you've just got to match your ammmo to yoour targets but there's added complexity in that you can vary the strength of your shot and get multiple targets with a single  rebounding blast. But hey, we all know the reason I put this up - it's got pirates in it!
