What is "starblade"

is a 3D space-based rail shooter arcade game that was released by Namco in 1991. It was notable for its early use of real-time 3D graphics, produced using the Namco System 21 "Polygonizer" arcade system board, and it is believed to have had a strong influence on the 1993 Nintendo game Star Fox. It was later ported to the Sega CD and 3DO in 1994. It was also released on the PlayStation as Starblade Alpha in 1995, and received a re-release in 2013 on iOS as part of the Namco Arcade application.
