R-Gray 0 is one of the three playable ships in RayStorm. It’s a prototype upon R-Gray 1 and an improvement upon RVA-818 X-Lay


This craft first appeared in PSX port of RayStorm exclusively through the 13 Ships Mode. Later it made available from player select menu in Layer Section II and RayStorm HD.

Developed as an initial prototype of R-Gray 1[1], R-Gray 0 lacks of Hyper Laser and Special Attack functions, and only having Manual firing mode (LS II version has both Auto and Manual modes). Unlike R-Gray 1's primary cannons, R-Gray 0's main guns fires in completely straight pattern similar to Rayforce's X-LAY. To compensate the lack of special weapons, its lock-on laser has the highest chain multiplier (x512) which makes this ship an excellent choice for scoring.

R-Gray 0 gets a major visual facelift in RayStorm HD, now more resembling the RVA-818 X-LAY than simply a palette swap of R-Gray 1.
