RayForce (also known as Layer Section, Galactic Attack, and Gunlock) is the first game in the of games but is the middle one chronologically, as RayCrisis was the prequel. It was created in 1994 by Taito. This is reputed to be the first game to revolutionize the "two attack layer" system, where the player can shoot in two separate layers: the same level as the player and a lower level beneath the player. Subsequently, the player had to use two different weapons in order to attack enemies on those layers.
