From the manual Tread lightly! The transport lanes of intergalactic space have been seeded with mines from an alien vessel. Use your mine destroying blaster to blow up the mines before they annihilate you! You may survive the floating mines, but beware of the fireball, magnetic, and treacherous fireball-magnetic mines... 13 fields, each one more difficult, await you! Note: This game comes preloaded on the Vectrex game console.
