Metal Storm (重力装甲メタルストーム Jūryoku Sōkō Metaru Sutōmu?, "Gravity Armor Metal Storm") is a 1991 side-scrolling platforming video game developed by Tamtex and published by Irem for the Nintendo Entertainment System. The game was released in North America in February 1991 and in Japan on April 24, 1992.

Although the NES does not directly support parallax scrolling, programmers continuously redrew the tiles making up the game's backgrounds in order to animate them scrolling at a different rate than the foreground, giving an illusion of depth, notably in the game's third and fifth stages where there is a "second" background layer that appears to scroll behind the first.


Known regional differences[edit]

Stage 1-1 of Metal Storm. Player is using reversed gravity.
  • The Japanese version features an opening cutscene before the title screen with credits in English and storyline in Japanese. The entire sequence is not present in the American release. This cutscene can only be unlocked in the American version with a Game Genie code, with some garbled graphics at some points.[citation needed]
  • Stage 6 of the Japanese version is significantly harder as the top and bottom of the screen are electrified. This prevents the player from wrapping around from top to bottom (or vice versa) without taking damage. In the American version, the barriers are not present, allowing the player to pass through the top or bottom of the screen without damage.
  • The Japanese version features extra narration in Japanese during the very last battle at the end of stage 7 that isn't present in the American version.
  • The Japanese and American versions have differently-colored palettes for some of the game's graphics. The Japanese version is brighter due to whiter backgrounds than the American version.
  • The Japanese version shows the phrase "warning" before a boss fight whereas the American version shows the phrase "red alert".
  • The Japanese version refers to the player's lives as "player" whereas the American version refers to them as "M-308 gunner", the name of the Mecha which the player pilots.
  • The text at the end of the game in the Japanese version is in English, despite the game's opening cutscene's text being in Japanese.

-The following is from the game's instruction manual.-

The year is 2501, and the dawning of a new century has brought mankind to the brink of disaster. The powerful LaserGun on the planet Pluto's battle station "Cyberg" is wreaking havoc. It was originally designed to protect Earth from hostile aliens, but, due to a computer malfunction, is systematically destroying all the planets in the Solar System! Most recently the Earth Nation watched helplessly as Neptune exploded.

The system's self-destruct device could stop the LaserGun, but it has mysteriously jammed and is aimed at Earth. Even if the device can be manually activated, there is still only a slim chance that Earth can be saved. Your mission is to enter Cyberg using the most sophisticated weaponry available, the M-308 Gunner, and unlock that self-destruct device!


Despite generally being well received by critics and reviewers, Metal Storm has remained a somewhat obscure release, as it was published by Irem without much publicity late in the life of the Nintendo Entertainment System. However, issue #22 (March 1991) of Nintendo Power not only had Metal Storm on its cover, but also featured a 12-page article on the game including a lengthy strategy guide. The issue's "Power Meter" review scores of Metal Storm were 3.8 out of 5 for graphics and sound, 3.7 out of 5 for play control, 3.7 out of 5 for challenge and lasting interest, and 3.7 out of 5 for theme and fun. The game's most notable feature is the ability to switch gravitational pull between the top and bottom of the screen at any time, requiring some strategizing from the player to pass through certain areas. The game uses a password system for continuing games at a later time.
