  • NO ORDINARY COMPUTER VIRUS

I. Setup & Premise

  • The pitch: You pilot the M-308 Gunner, a walking war machine that can flip gravity and fight. The job is to break into a malfunctioning battle station and blow it up before it blows up Earth.
  • The premise: It is the year 2501. Humanity has colonized the solar system, and a defense station on Pluto called Cyberg houses a giant LaserGun built to fend off alien invaders.
  • The gun malfunctions, turns on its makers, and starts destroying planets. Neptune is already gone, and Earth is next (how is that the order?).
  • A fun bit of manual flavor The manual gives the M-308 Gunner a full spec sheet: 9 feet tall, 2100 pounds, built from "Geopolyum Alloy," 1300 KW generator, and one listed Special Function: Gravity Flip.
  • Developed by Tamtex, a Tokyo studio that was a subsidiary of arcade giant Irem, and published by Irem.
  • Combat is light and the whole game is built around one idea: flipping yourself between the floor and the ceiling to survive. The cleanest modern comparison is VVVVVV, the gravity-flip indie game.

II. What Makes It Stand Out

  • The entire game is the gravity flip Press Up and the jump button together and you fall upward and land on the ceiling. Press Down and jump to flip back.
  • Its headline trick is simulated parallax scrolling, layered backgrounds moving at different speeds for a sense of depth, which the NES could not do on its own. Tamtex faked it with a custom mapper chip in the cartridge and clever memory bank switching.
    • The result is up to two independently moving background layers
    • The mech is a big, smoothly animated sprite and the bosses are multi-part machines that look straight out of Gundam or Macross
  • Metal Storm landed the cover of Nintendo Power issue 22 with a 12-page strategy guide, yet it was a commercial failure. (Wikipedia)
  • The US cartridge has the game's story intro cutscenes sitting in the code, just switched off. They can be turned back on with Game Genie codes (SNKEPULO and OOKEZLVP).
  • There is also an R-Type ship cameo hidden in the game.

III. Gameplay Structure

  • Stage layout Six main stages, each split into two acts, then a seventh stage that is a climactic boss rush.
  • The environment is the real enemy
    • Hazards switch on and off depending on which way is down for you: lasers, crushing blocks, and gates that flip when you flip, where simply flying around a gate kills you instantly.
    • Later stages add screen-wrapping, a level that loops endlessly as you fall, a moving cage you have to stay inside, and platforms that scroll up and reappear at the bottom to scramble your sense of up and down. (Hardcore Gaming 101)
    • The first stage has a defined floor and ceiling, but the second stage does away with this, creating an infinite vertical environment where the floor is the ceiling and the ceiling is the floor, and you can step off a platform and fall down to land back on the same platform. That's the mechanic graduating from "neat trick" to "rethink how space works." There are even infinite-drop sections where you fall forever until you move left or right to catch a platform. Great bit to describe out loud because it sounds impossible until you picture it.
  • Three main power-ups, only one active at a time:
    • P upgrades your shot to punch through surfaces,
    • S is a shield
    • G turns you into a damaging fireball each time you flip.
    • Otherwise you die in one hit, and grabbing a shield wipes whatever weapon you were holding, which is a brutal trade-off.
  • For an Irem game it is still relatively forgiving: unlimited continues and a password system.

IV. Unique Gameplay Elements

  • Almost every boss forces smart gravity use. The first one has a weak spot that jumps between three points, two of which you can only hit while upside down, all while dodging ring shots.
  • Later fights include a wall of laser turrets that makes you jump nonstop, a mech that quarters the arena with crossing beams, a robot that bounces around a cage, and a transforming machine with three forms.
  • Expert Mode
    • Beat the game and you unlock a second quest. Enemies and bosses get tougher, hazards are reconfigured, and power-ups are stripped down.

V. Reception & Legacy

  • Loved by critics, ignored by shoppers
    • Reviews were strong: EGM 7.75 out of 10, Computer and Video Games 88, Mean Machines 88 percent, and Game Player's called it a must-buy. (Wikipedia) But it sold poorly
  • IGN ranked it the 46th best NES game, 1UP called it a hidden gem, and CBR named it the best NES game released right before the SNES.
  • Low print run plus rising reputation turned it into a pricey collector's item, with copies going for as much as roughly 200 dollars.
  • In 2019, Retro-Bit and Limited Run Games reissued it, based on the better Japanese version and translated into English for the first time, complete with an M-308 Gunner figurine modeled on the Nintendo Power cover. (Wikipedia / reviews of the 2019 release)

VI. Sequels and Spinoffs

  • No true sequel, but there is a "director's cut" There was never a Metal Storm 2. The closest thing is the Japanese Famicom version, Jūryoku Sōkō Metal Storm, or "Gravity Armor Metal Storm," which arrived more than a year after the US release. (Wikipedia / The Cutting Room Floor) It is the more complete build: a full intro cinematic, extra dialogue, the correct white mech, a tweaked gravity-flip input, and an even nastier stage 6 with electric barriers on the ceiling and floor. The 2019 reissue is a translation of this version. (Hardcore Gaming 101 / Wikipedia)
  • Japan added the "Gravity Armor" subtitle because an executive felt the plain name "Metal Storm" did not convey what the game actually was, according to pixel artist Kiyoshi Utata. (The Cutting Room Floor)

VII. Essential Games List Vote

  • Case for Essential
    • It is one of the most technically jaw-dropping games on the NES, with depth effects the hardware was never built to do.
    • The gravity flip is a genuinely original idea, and unlike its peers the whole game commits to it, with level and boss design to match.
    • It is tough but fair.
  • Case against Essential
    • One-hit deaths and the shield-wipes-your-weapon rule can feel harsh.
