A vertical-scrolling shooter released by Namco worldwide in 1994. Controlling the Fighting Ray starships (red for 1P and blue for 2P), gameplay involves shooting down enemies and avoiding both them and their projectiles across six different stages, known as "areas" in-game. Destroying large cylindrical enemies named "Capsules" will drop a power-up item that will upgrade the player's abilities and give them access to special weapons. Some weapons are permanent until death, while others have a time limit that will revoke the item when it reaches zero. Each stage has a boss that must be defeated, having a weak spot that must be shot to destroy it. After completing all six stages, a seventh "Challenging Area" will begin, a repeat of the first area with much faster enemies and lighting-quick projectiles.
