Steel Battalion (Japanese: 鉄騎 Hepburn: Tekki) is a video game created by Capcom for the Xbox console where the player controls a "Vertical Tank"—a bipedal, heavily armed mecha. To control the tank and play the game requires the use of a large controller made specially for Steel Battalion. The controller has two control sticks and around 40 buttons. Only limited quantities were made available. These quickly sold out, making the game a collector's piece. It has since been re-released in limited quantities worldwide, with blue controller buttons distinguishing it from the first edition with green buttons.
