is a 1985 horizontally scrolling shooter video game developed and published by Nichibutsu for arcades. It was ported to the Nintendo Entertainment System, released in Japan on March 19, 1986, and by FCI in North America in October 1988. The game was also ported to the Commodore 64, ZX Spectrum, and Amstrad CPC by Ocean Software and released on their Imagine label in 1987.
The three-headed mechanical dragon found as a boss character in the game, known as Babylon, strongly resembles Mecha-King Ghidorah from the Godzilla franchise. Hamster Corporation acquired the rights to the game alongside Nichibutsu's intellectual property, and released the game as part of their Arcade Archives series for the PlayStation 4 in 2015 and the Nintendo Switch in 2020. Hamster scheduled the NES version of MagMax to be re-released as part of Console Archives for the Nintendo Switch 2 and PlayStation 5.
Players control the titular spaceship in an attempt to completely construct the ship into a giant robot and to destroy any enemies attempting to stop it. The ship must avoid various obstacles while shooting enemies on a 3D field. After a successful transformation into the robot, the ship gains increased mobility, while the gameplay becomes that of a typical horizontal scrolling shooter.
In Japan, Game Machine listed MagMax as the second most successful table arcade unit of April 1985.
