After receiving numerous complaints about the Level 13 bug in Minestorm, GCE sent this fixed version of the game on cartridge to anyone who asked for it. Also, in the later versions of Vectrex consoles, the fix had been made in the built-in game. The cartridge version is one of the rarest Vectrex cartridges around. 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!
