Press Button 1 at the title, then Button 1 on the war-plan map to launch the first sector.
Clear all four sector nodes, select G, and defeat the world's guardian.

Select **Normal / Relaxed** with Left or Right on the title. Relaxed gives five starting lives, reduced damage and gradual energy recovery; Normal gives three lives and arcade damage. Start with Relaxed if you are learning the inertial controls.
