Blaster Master is an old U.S title sold by Sunsoft in 1986 for the Nintendo Family Computer. It was a hit all across the U.S. selling 750,000 copies. This success led to two sequels being made: Blaster Master Boy in 1990 for Game Boy, and Blaster Master 2 in 1993, for Sega Genesis. All versions of the game received tremendous fan support. Sunsoft made the decision to go into production with a sequel, six years after the previous version. Blaster Master "Enemy Below" for GBC is the result.
