The human of the 26th century created a weapon of "ecological destruction". This weapon was called "Bydo", a self-replicating organism. They were placed in a container the size of the moon and were intended to be sent via wormhole to warp to the enemy system and destroy the planet. However, an "error" liberated the Bydo. They rampaged in the system until they were picked up by a "special weapon" and sent to another dimension. The Bydo evolved in said dimension and found a way to appear in the 22nd century earth. The R-9 "arrowhead" spaceship is send on a mission to stop them.
The most notable feature of R-type is the "Force", the Force (a tamed bydo) is an indestructible sphere that can attach to the back or the front of the player ship to absorb small enemy shot or to be thrown at enemy. The Force start initially as weaponless

There's also a substitute of the force, called the "Bits", they are small round-object similar to the Force, and the player can have two of them, One above and the other below. Another unique feature is the charge shot, by holding the shoot button, it will grow stronger. Fully charged, a shot can cut through many small enemies.
