Codex Gamicus

Mine Storm is a game released for the Vectrex. It was a built-in game that came with every Vectrex unit. It was also released in a 3D version that required the use of the Vectrex 3D Imager and as a bug-free replacement cartridge called Mine Storm 2 (see Bugs section).


Gameplay is similar to Asteroids. The player moves around the screen shooting at star-shaped mines of various sizes and have various mannerisms. All the dots on a screen can potentially turn into mines; once a mine is shot, two dots on the screen will turn into medium-sized mines, which will then turn into two small mines when shot. When all dots have been turned into mines on a screen the Minelayer will come out, laying mines in its wake until the player destroys it.

Making contact with any mine, fireball, space dust, alien force or Minelayer will destroy the player's ship and the game will end once there are no more reserve ships left. Extra ships are earned after every four levels are cleared. The Escape function acts as Hyperspace, which moves the player's ship to a random area on the screen.

Mine types[]

  • Floating Mines—regular "dumb" mines that just drift around
  • Fireball Mines—these will launch a fireball when shot, usually right at the player's ship
  • Magnetic Mines—follows the player around
  • Magnetic-Fireball Mines—combination of the behavior of Fireball and Magnetic Mines
  • Space dust—looks like dots, acts like Floating Mines (i. e. they're deadly to touch)
  • Alien forces—combination of Space dust and Magnetic-Fireball Mines

  • With the infamous level 13 bug, the game would usually crash if a player was able to clear out this level. An extra printed sheet was added to the instructions advising players to press the reset button if their Vectrex screen went blank after clearing this level. Also, a Minestorm 2 cartridge was made available for free upon request for Vectrex owners who wrote to GCE, which was bug-free. This is one of the most rare and sought after Vectrex cartridges nowadays.
  • In addition to the above glitch, even if a player makes it past level 13, the game behaves strangely, as there is a brief cinematic bit at the end of every level where the player's ship is sucked up from whatever area of the screen it is at to the middle while stars seemingly project from it (perhaps it is hitting warp to jump to the next level). If the player stays as close to the center as possible at the end of every level after 13, they will continue to advance; however, there are many times when a level skips several numbers for some reason.


  • Mine Storm is commonly mistaken as to being spelled as "Minestorm". It is clear by looking at the instruction booklet that came with a Vectrex unit or by starting the game either on a Vectrex or an emulator that "Mine Storm" is two words when the title screen comes up.
  • There is invisible Space dust on level 89, which, if a particle of Space dust makes it off the edge of the screen, instead of wrapping around to the opposite screen edge, it disappears, and if it is not shot in time it will not turn into mines, which the player will be stuck on that level if they do not destroy all of the Space dust particles possible.
