This is a frantic and surprisingly addictive shooting game with vector graphics, written as an experiment in AGS. With your triangular ship, shoot down all the evil polygons before they do the same to you! Featuring twenty different enemies that wander, chase you, snipe from the corners, or blast you with a frickin' laser, and over fifteen powerups to boost your speed or firepower. Plus, it keeps track of high scores so you can brag about them to your friends.
Vector Vendetta, Linux version. Works under Ubuntu and most variants.
