RayCrisis is a 1998 vertically scrolling shooter arcade video game developed and published by Taito. A PlayStation home release was published in 2000 as RayCrisis: Series Termination. It is the third in the Ray series of games serving as a prequel to RayForce. The gameplay of RayCrisis is based on RayForce which features a viewpoint given to the player with an overhead perspective. The game is a vertically scrolling shooter with a "virus infiltration" theme: the player plays the role of the Waverider computer virus and the enemies are Con-Human's antibodies programmed to terminate any virus—including the player—inside the supercomputer's system.
