X倍增

X Multiply is a 2D side-scrolling shoot'em up, a follow up to Irem's R-Type with similar gameplay. While the game's background story still features the standard alien invasion, the action takes place inside a woman's body, because the aliens are microscopic creatures. The player controls the miniaturized X-002 fighter. He flies forward to the right, avoids attacks and kills aliens. As opposed to Force Pods, the ship has flexible, indestructible tentacles. These can be used as a shield, which is important because a single hit is deadly for the player. As is common for the genre, it's possible to pick up power-ups, like special lasers.
