X Multiply is a side-scrolling shoot 'em up published by Irem, and similar in style to their earlier R-Type. Instead of the Force pod, however, the main power-up apparatus takes the form of two flexible tentacles. The tentacles are invulnerable to all enemy attacks, and can be positioned with careful maneuvering of the player's spaceship. Konami's Xexex is based on a fusion of this weaponry with the Force system of R-Type.
