This Mega Drive port was developed and published by Data East on March 29, 1991 in Japan. Although the graphics and stage designs are similar to the arcade version's, the controls were changed to accommodate for the lack of a rotatable joystick. Four control configurations are available. The default controls allows the player to aim at the direction he is moving and keep his aim steady by holding down the B button. The other configurations are closer to the arcade version's controls, allowing the player to rotate the character's aim clockwise, counter-clockwise, or alternate between the two. The player fires his weapon in automatically, which can be toggled on and off with the A button. Unlike the arcade version, the Mega Drive version is single-player only.
