Replicart is an action game originally developed by Dual and published for the MSX2 in 1987 by Sony. It is to the original Snake game what Arkanoid is to Breakout; an upgrade that takes the core features of the game and expands upon them by adding enemies, power-ups and more elaborate play settings. This original version contains 300 different stages where the player must navigate a robotic snake through mazes in an effort to collect a required number of pieces before the exit will open. The snake's length extends by one unit for every piece collected. If the snake's head touches any of the walls, enemies or its own body, it is destroyed and the player loses one life.

In 1988, Taito purchased the rights to the game and published it on two more systems. The conversion to the NEC PC-8801 is roughly a straight port and contains no significant differences. However, the conversion to the Famicom Disk System is quite different. The number of levels has been reduced to 100, but between every 10 levels, a boss battle occurs in which the player must chase a monster around the screen and blast it until the monster takes enough damage. A bonus level is provided for the player after each boss is defeated before they progress to the next level.

The game takes place at the end of the 21st century. A gigantic snake-like alien called Sonada invades Earth and constructs a base under the soil. Sonada attacks various locations, stealing precious resources, and appears invulnerable to all forms of modern offenses. Engineers regroup and construct a base where a new weapon can be developed. They create the Replicart in the image of Sonada, and give it the power to convert resources into new material that can extend the Replicart and increase its strength until it reaches enough power to destroy the invader.


Note that the Replicart moves forward at all times under its own power and speed. The only thing that the player can do to control the Replicart is to steer the head to the left or right.

  • Left dpad: Turn the head of the Replicart 90 degrees counter-clockwise.
  • Right dpad: Turn the head of the Replicart 90 degrees clockwise.
  • B button: Press the B button to fire the Replicart's weapons whenever a boss is present, or when you have collected the F power-up.


In Replicart, the player begins each stage by entering in from the right side of the screen. Play is paused until the player presses a key to begin the stage. Once moving, the Replicart will not stop moving. The player must steer the Replicart through each stage by rotating the head 90 degrees to the left or to the right. In order to exit a stage, the player must collect a predetermined number of Biteslimes. For every Biteslime collected, the length of the Replicart extends by one unit (unless the Keep power-up is activated.) In order to survive the stage, the head of the Replicart must not collide with any wall, any part of itself, or any enemy. Some stages contain simple enemies that move about the screen. When the exit opens, these enemies transform into a different, sometimes large enemy that can pass through barriers. If no enemies are present on the stage, one such enemy will appear after the exit opens.


Power-ups can be found by moving the snake through particular locations on certain stages. Some power-up locations are initially visible, while others are hidden. Once the head of the Replicart touches a power-up, it will be revealed, but it can't be collected and activated until the body of the Replicart has completely passed over it. Some power-up tiles do not contain power-ups at all, but rather hide empty holes that will kill the player if he or she falls into one.
