Also known as: 超鋼戦紀キカイオー, キカイオー
Choukou Senki Kikaiou, (released elsewhere in the world as Tech Romancer) is a 1998 3D fighting Arcade Video Game by Capcom that draws heavily from the various sub-genres of Mecha anime.
In the game the player controls a giant robot which is used to fight another robot in one-on-one combat. Kawamori Shouji and the rest of Studio Nue (the animation studio responsible for the mechanical designs from many robot anime series including Choujikuu Yousai Macross, Top Wo Nerae!, and Mobile Suit Gundam 0083: Stardust Memory) designed the robots in this game.
It was ported to the Sega Dreamcast console later in the same year.
