Twin Cobra

Did You Know?

• The game ran on the Toaplan Twin Cobra hardware, which used a Motorola 68000 CPU at 7 MHz, a Z80 CPU at 3.5 MHz, and a Yamaha YM3812 sound chip.
• Toaplan's Flying Shark used the same arcade hardware board.
• In Japan, Game Machine listed Twin Cobra as the fourth most-successful table arcade unit of January 1988.

Gameplay

Twin Cobra is a military-themed vertically scrolling shoot 'em up in which players control an attack helicopter through ten levels, each ending with a boss. The scenery scrolls continuously until a helipad is reached. Players have a standard shot that travels the screen's height and three bombs that obliterate enemies within their blast radius; collecting "B" icons adds bomb stock. Power-up items appear via enemy carriers: color-changing icons (red, blue, green, yellow) switch between four weapon types, while "S" icons increase firepower. Other items include 1-ups and star-shaped gold medals worth 3000 points. Players start with two lives; bonus lives are awarded at point thresholds. Depending on region, the game uses either a checkpoint system or a respawn system where the ship reappears at the death location. Collision with enemy fire or enemies costs a life and reduces firepower to its original state. Losing all lives ends the game unless more credits are inserted. After the last stage, the game loops with increased difficulty and denser bullet patterns.

Development

Composers Masahiro Yuge and Tatsuya Uemura recounted that the basic structure was decided during development of Slap Fight, focusing on the excitement of shooting and dodging. They settled on the bomb and shot system, with Yuge stating that firing a bomb relieved stress from players. The Japanese title's word "Kyūkyoku" derived from a translation of Going for the One, an album by Yes; the president of Toaplan initially rejected it, but Yuge was determined to implement it. The bomb concept arose during Tiger-Heli's development, intended to provide an aggressive feeling rather than defense, though enemies were made tougher to maintain balance. The soundtrack used FM synthesis and guitar.

Release

Twin Cobra was released in arcades worldwide in October 1987 by Taito in Japan and Europe, and by Romstar in North America. A music album co-published by Scitron and Pony Canyon came out in Japan in November 1988. The game was ported to multiple platforms by third-party developers: PC Engine (1989, by A.I Company, Japan only), NES (1989, by Micronics, Japan by CBS/Sony, North America by Sammy), Sega Genesis (1991, by GRC, published by Treco in Japan, Sega in North America, Tectoy in Brazil), X68000 (1993), and FM Towns (1994). Banpresto released the compilation Toaplan Shooting Battle 1 for PlayStation in Japan on 30 August 1996, including both arcade versions of Twin Cobra and its prequel. In November 2019, MOBIRIX Corporation re-released it for iOS and Android in Japan as Kyukyoku Tiger Classic. A Samsung Smart TV port is available. M2 included it in the Kyukyoku Tiger-Heli compilation for Switch and PS4 in 2022. Bitwave Games ported it to Steam in February 2023.

Legacy

Twin Cobra nearly had a sequel from Toaplan, but the company shut down in 1994. Taito then allowed Takumi Corporation, a Toaplan offshoot, to finish Twin Cobra II as their debut game in 1995. A Sega Saturn port followed in 1997 under the name Kyukyoku Tiger II Plus. Seibu Kaihatsu artist Toshinobu Komazawa said his company took ideas from Twin Cobra for Raiden. Artist Perry Sessions named it a key influence on Super XYX. The rights now belong to Tatsujin, a company founded by former Toaplan employee Masahiro Yuge, which has been part of Embracer Group since 2022.
