Developed exclusively for Xbox 360 and produced by Square Enix (they also do something called Final Fantasy), Project Sylpheed is billed as a colorful arcade-style space combat game, which sounds about right to us. You can find out for yourself, with a demo on Marketplace.
Square says, "If the beautifully animated characters and environments don't catch your eye, piloting the fully weapon-customizable fighter ship through exhilarating battles with swarms of enemy ships and immense vessels will." And they might be right.
Go download the demo and have a look. While the monster demo is downloading, feel free to browse the official website at your leisure.
