Raycrisis is part of a series of "Ray" shooting games and serves as a prequel to the first game's plot in RayForce . The game takes place where two players can fight together, but on playstation version there isn't 2-player mode.
You have two weapons at your disposal: a vulcan gun and a lock-on missile attack. You can also do special attacks if you use the lock-on system to its maximum level. The graphics are in 3D, while gameplay mechanics are still in 2D.
The player's ship is the Waverider computer virus, which needs to get inside the Con-Human supercomputer's system. All enemies encountered are antibodies programmed to terminate any virus.
The levels are called Self-Area, Emotion, Consciousness, Intelligence, Memory, and Consideration, each reflecting Con-Human's details of sentience. Finally, you need to fight against the Dis-Human Antibody, and Infinity, which is Con-Human's heart.
