The premise behind this game is that of a western, but set in the future, and in space. There is a plot but the gameplay focuses on fast 'n' furious arcade action. You are a Star Ranger and it's your duty to protect the human frontier from alien attack.

You and your wingman must hyperspace between points to protect bases and civilian ships, while managing these conflicts you must also make a pitstop if your ship becomes to damaged, energy too low or to load up with missiles.
