Defiance

Defiance puts you in the pilot seat of an experimental LAV-6 SABER, a one-man hovercraft armed with a variety of energy weapons, rockets, and smart-bombs. When a series of tests at a military manufacturing plant on the planet Calchon go horribly wrong, you find yourself under attack by hundreds of malformed, biomechanical monsters. You'll have to fight your way to freedom as you discover what exactly happened to bring these creatures to Calchon's doorstep.
