Tiger Heli

Tiger-Heli is a vertically scrolling shooter game. The player controls the Tiger attack helicopter, fighting against air and ground enemies such as tanks, gunboats, artillery, and aircraft. Other targets include buildings, level crossings, cars, fuel depots, tents, and mine carts. The helicopter is equipped with two weapons: short-range missiles and bombs.

The missiles can hit both air and ground targets. The bombs can destroy any enemy and their bullets within range when fired. If enemy bullets hit a bomb carried by the helicopter, it will detonate automatically. The game employs a scoring system; the player's score increases as targets are destroyed.

Tiger-Heli was the first shoot 'em up developed by Toaplan. It was programmed by Masahiro Yuge, Tatsuya Uemura, and Yuichirō Nozawa. Yuge, Uemura and Nozawa had worked for the Japanese companies Orca and Crux, before both went bankrupt and they joined Toaplan. Nozawa had previously created the shooter Gyrodine, while Yuge and Uemura had worked on the action game Performan, their first game at Toaplan.

Performan was not as successful as the team had hoped, so they stepped back and revisited Vastar (1983), a shooter they previously made at Orca and which had performed well. They decided their next project would be a shooter, under the working title Cobra.

According to Masahiro Yuge, Tiger-Heli generated a lot of income during its location test in Meguro and was a big hit. In Japan, Game Machine listed it in their October 1, 1985 issue as being the most-popular arcade game for the previous two weeks. Micom BASIC Magazine considered Tiger-Heli a monumental work, but noted that its gameplay was slow and lacked balance. Haoh magazine enjoyed the thrill of dodging enemy bullets in the game, but felt the bombs were not useful due to their limited range. AllGame's Anthony Baize found the game fun and its graphics ahead of their time, but faulted the limited range of bombs and lack of power-ups.

Retrospective commentary for Tiger-Heli has been mixed. Hardcore Gaming 101's Nick Zverloff wrote that "Tiger-Heli is a little rough in retrospect, but it's also about on par with other shooters from 1985". In a 2021 review of Kyukyoku Tiger-Heli, Nintendo Life's Will Freeman called the game a classic of its time, but felt that it has not aged well compared to its contemporaries. Likewise, M!

The success of Tiger-Heli helped establish Toaplan as a leading developer of shooters during the 1980s and 1990s, which would continue to characterize its output. The game also introduced the concept of the bomb, a mechanic that Toaplan would continue to develop in later games, becoming its hallmark and a staple of the shoot 'em up genre.

As printed circuit boards (PCBs) slowly advanced, a sequel to Tiger-Heli was conceived out of a desire to remove the stress induced by its predecessor, offering a fun and deep experience for players as its core concept. Twin Cobra was released for arcades in 1987 and was ported to the NES, PC Engine, Sega Mega Drive/Genesis, X68000, and FM Towns. In 1994, Toaplan declared bankruptcy, but Masahiro Yuge and some of the staff transferred to Takumi Corporation. Takumi acquired the Twin Cobra trademark and developed a sequel, Twin Cobra II, released for the Taito F3 System in 1995.
