You may choose from three available models for your base chassis. Then, when you acquire emeraldium crystals, you may purchase improvements for your ship. The Crab is a heavy, strong ship. It carries a large main cannon, allowing many sustained shots. Because of all this armor and gear, however, it is slow and hard to maneuver. The Mantis is based on a racing craft. Its slender body contains both powerful thrusters and swift maneuvering jets. It carries relatively weak weapons, however. The Moth is a time-honored favorite, containing a mix of decent weaponry and reasonable engines. As a jack-of-all-trades, however, it is a master of none.
