Star Defender II is a new Galaga-inspired game that is nothing but a continuous survival marathon that is sure to exhaust even the most experienced players. The game is 100 levels long, jam packed with amazingly detailed and uniquely different species of aliens (total of thirty) and is undoubtedly one of the toughest scrolling shooters in the world. So tough, in fact, that David Laprad of Gamextazy.com rightfully wrote that the only thing the game lacks is mercy.
