Zero Wing

Zero Wing is a science fiction-themed side-scrolling shooter similar to Hellfire, where players assume the role of Trent taking control of the ZIG space fighter craft through eight increasingly difficult levels, each with a boss at the end that must be fought before progressing any further, in a last-ditch effort to overthrow the alien cyborg CATS as the main objective. As far as side-scrolling shooters go, the title initially appears to be very standard, as players control their craft over a constantly scrolling background and the scenery never stops moving until the stage boss is reached. A unique gameplay feature is the "Seizer Beam" system; during gameplay, players can grab certain enemies and hold them as shield against enemy fire or launch them against enemies. There are three types of weapons in the game that can be switched between after destroying incoming carriers by picking up a color-changing item ranging from the "Red Cannon" shot, the "Blue Laser" and the "Green Homing" missiles. Each weapon can be upgraded by picking up an item of the same color. Other items can also be grabbed along the way such as speed increasers, 1UPs and a bomb module capable of obliterating any enemy caught within its blast radius that can also be triggered after taking enemy hits. Depending on the settings in the arcade version, the title uses either a checkpoint system in which a downed single player will start off at the beginning of the checkpoint they managed to reach before dying, or a respawn system where their ship immediately starts at the location where they died. Getting hit by enemy fire or colliding against solid stage obstacles will result in losing a life, as well as a penalty of decreasing the ship's firepower and speed to his original state and once all lives are lost, the game is over unless the players insert more credits into the arcade machine to continue playing. The game loops back to the first stage after completing the last stage as with previous titles from Toaplan, with each one increasing the difficulty and enemies fire denser bullet patterns as well as spawning extra bullets when destroyed. == Synopsis ==

The backstory of Zero Wing varies between each version, but the plot within the game itself remains consistent. Set in 2101, the game follows the signing of a peace treaty between the United Nations (also translated as the Milky Way Federation) and CATS, a space pirate organization, who later breaks the covenant and takes control of the Japanese/Federation space colonies. The protagonist, Trent, pilots a ZIG spacecraft that managed to escape from a mothership destroyed by a representative of CATS. His aim is to defeat enemy forces, avenge the mothership and its crew, and liberate Earth. However, in the PC Engine version, the story is different. CATS is replaced by an organization called Abigor, led by a man named Ludwig and his right-hand woman, Seiren. Abigor attacks the Galactic Federation, and the ZIG, piloted by Masato Tachibana, is sent to repel them. It is eventually revealed that the Federation dispatcher's sister, Airen, who had been working as an undercover spy to alert the Federation about Abigor's attack, is arrested by Seiren and turned over to Ludwig. After Ludwig chooses to spare Airen's life, Tachibana communicates with Ludwig, who challenges him to a battle with the condition that Airen will be returned if Tachibana wins. Tachibana accepts and destroys Ludwig's ship, after which Ludwig relinquishes Airen before committing suicide. Airen and Tachibana then celebrate their victory before returning to Earth offscreen. == Development ==

Zero Wing was created by most of the same team that previously worked on several projects at Toaplan, with members of the development staff recounting its history through various Japanese publications. Toshiaki Ōta was at the helm as development chief and also served as programmer alongside Hiroaki Furukawa and Tatsuya Uemura. Uemura also acted as composer along with Masahiro Yuge and Toshiaki Tomizawa. Artists Miho Hayashi, Naoki Ogiwara and Shintarō Nakaoka created the artwork while Sanae Nitō and Yuko Tataka served as character designers. Uemura stated that Zero Wing originally started as a project not intended for commercial launch to train new recruits at Toaplan, handling training for new hires while using his work and engine from Hellfire before ultimately deciding with releasing the game to the market, which made it a more practical learning experience for the new developers. Uemura, however, felt that both stage design and characters were "cobbled together", leading the game's world being "kind of a mess" and he also stated the project turned into a "battle royale", as staff from both Hellfire and Truxton were mixed with the new recruits. Both Uemura and Tataka have stated that working with the Mega Drive proved to be difficult due to several restrictions imposed by the hardware. The Mega Drive port features arranged music by Noriyuki Iwadare. The PC Engine CD-ROM² version was outsourced by an "acquaintance" from defunct developer Orca, with Uemura handling sound. To expand the plot, the Mega Drive version added an introductory sequence to the game. This introduction does not appear in the arcade original nor in the PC Engine CD-ROM² versions; rather, a different intro takes place with a blue-windowed ZIG. The PC Engine CD-ROM² also added two new levels: 5th (Deeva) and 10th (Vacura). == Release ==

Zero Wing was first released in arcades in October 1989 In 1989, an album containing music from the title was co-published exclusively in Japan by Scitron and Pony Canyon. and later in Europe by Sega in July 1991. The Mega Drive port was later released in North America by independent publisher Retro-Bit in 2020. Zero Wing was included as part of the Toaplan Arcade 1 compilation for Evercade, released in December 2022. Zero Wing was re-released on the Nintendo Classics service in June 2022. Bitwave Games and Toaplan jointly released Zero Wing on Steam and GOG.com in February 2023, both as a standalone title and as a game bundle with Twin Cobra, Truxton, and Out Zone. The Steam version includes several game enhancements, such as an updated graphics, rewind option, achievements, online leaderboards, sidebar indicators, and a new Very Easy mode. == Reception ==

In Japan, Game Machine listed Zero Wing as the fourth most successful table arcade unit of November 1989, outperforming titles such as Jitsuryoku!! Pro Yakyū and U.N. Squadron. The game received a positive critical reception upon release. Computer and Video Games scored it 93%, including ratings of 92% for graphics, 93% for sound, 90% for playability, and 89% for lastability. They praised "the great intro sequence", "super-smooth gameplay, beautifully defined graphics, rocking sound track, amazing explosions and incredible end-of-level bosses", concluding that it is "the game which breaths (sic) new life into shoot 'em ups on the Megadrive". == Legacy ==

Zero Wing was the last side-scrolling shoot 'em up title to be developed by Toaplan, as the developers believed they did not know how to make a side-scrolling shooter interesting, despite positive reception from players. Translations were handled internally by the design team, not a professional translator. Zero Wing is also of interest in the field of translation studies in the context of its multiple endings. Many of those endings referenced then-current Japanese popular culture in ways that would have been hard to translate across cultures, and suggests that the text was written by someone who grew up in the 1960s or 1970s. == Notes ==
