Mag Max was released on March 19, 1986 in Japan for 4900 Yen.
This game is the first game made by Nichibutsu on the Famicom.
The original Mag Max arcade game was released by Nichibutsu in 1985. Unlike the Famicom version, the arcade game featured a horizontal parallax scrolling effect which added an incredible depth to the above ground sections (which was definitely an unique feature, especially for a shooter released in 1985).
