I downloaded the demo for this and almost immediately bought the full game. It's a lot of fun and interestingly enough adds a new dimension to the Dual Stick shooters, in that your satellites act independently one you drop them off and give them a direction to shoot. But you can call them back whenever you want. So when you see the bad guys materializing, you can set up your sats in a formation that will help you defend. Like most Arcade ports nowadays, the game is very psycadelic and sports a cool sound track. I spent some of my CC points on it, so I need to refuel my points to 1200 this weekend, but it's a worthwhile little arcade.
