In this colorful shooter, the player controls a starship with two basic attacks - Twin bullets that hit airborne enemies and Drop bombs that hit ground objects indicated by the target in front of the starship. Throughout each planet, the player will find shops in which better equipment can be purchased for the ship's engines (to increase speed), missiles (for better but limited firepower), bombs (greater but limited destruction on ground targets), barriers (to protect the starship) and option (which sells mixed equipment). The credit needed for purchases is found from destroyed airborne and ground targets. The player can find letter pickups, which spell the words EXTRA, MONEY, BLAST and SECRO. If all the letters of one word are collected, the player earns a bonus that matches the word. The player loses a life if the starship is destroyed (from an enemy projectile or collision with an enemy). At the end of a planet, the player must repeatedly bomb or shoot a boss enemy to proceed to the next planet.
