Bosconian

The objective of Bosconian is to score as many points as possible by destroying enemy missiles and bases. The player controls the Starfighter, a ship that can move in 8 directions and fires both forward and backward simultaneously. Throughout the game, the Starfighter stays affixed to the center of the screen as it moves. During each round, several green enemy bases — known as "base stars", or "Bosco bases" — appear, all of which must be destroyed in order to advance to the next round.

The number of Bosco bases increases with each round. Each Bosco base has 6 globe-like cannons arranged in a hexagon around a central core. To destroy a Bosco base, the player must either shoot the core or destroy all 6 cannons, the latter of which gives the player extra points. In later levels, cores begin defending themselves by opening and closing while launching missiles.

The game takes place after the fictional Rock War, an intergalactic conflict between mankind and aliens which ended with the aliens destroying (nearly) all of Earth's cities with missile-firing space stations, known as "Orbitals", and enslaving all (surviving) humans. In an attempt to fight back against the aliens and regain their independence, humans built a spacecraft known as the Starfighter with the best technology they could find, but only one such vehicle could be built. The game involves the unnamed pilot of the Starfighter defeating the aliens to save Earth.

Designer Seiichi Sato was tasked with coming up with ROM-swappable games using Galaxian, Pac-Man, and Rally-X boards. These all became Galaga, Dig Dug, and Bosconian. Sato originally worked on both this game and Galaga together with Shigeru Yokoyama, but the two gradually began working on just one game each. A woman from Namco's sales department was originally brought on to provide the game's voice lines due to the popularity of female voices in American science fiction. Her takes ended up being scrapped in favor of those by Hideyuki Nakajima, the president of Namco America at the time.

In Japan, Bosconian was the seventh highest-grossing arcade game of 1981, according to the annual Game Machine chart. Game Machine later listed Bosconian as the 22nd most successful table arcade cabinet of August 1983. However, the game was less successful internationally. Due to the rising popularity of Galaga and a shortage of arcade cabinets for the game, many of the Bosconian cabinets that were not selling were converted into Galaga cabinets.

Upon release, Bosconian received generally positive reviews. Video Games Magazine referred to the game as a "treat for Galaxian fans" and opining that, while it did not "break ground insofar as graphics, sounds, weaponry, and antagonists are concerned", it had "a terrific eight-way joystick that has great maneuverability". Electronic Games called it "a real space-gamer's delight", highly praising its 360-degree movement and the ship's simultaneous front-rear fire, which they noted made it the first game to feature either element, as well as its graphics, gameplay, and other mechanics.

Bosconian has been considered influential for other multidirectional shooters, and has been called "a granddaddy of the multidirectional shooter" by Retro Gamer. Bosconian served as the main inspiration for the 1983 game Sinistar and as an inspiration for the 1982 game Time Pilot.

Bosconian later appeared in several Namco Museum compilations for PlayStation and other consoles, including Namco Museum Vol. 1 for the PlayStation in 1995, Namco Museum Battle Collection for the PlayStation Portable in 2005, Namco Museum 50th Anniversary for the PlayStation 2, GameCube, Xbox and Microsoft Windows later that year, Namco Museum Virtual Arcade for the Xbox 360 in 2008, the Wii's Virtual Console in 2009, as well as Namco Museum Megamix for the Wii in 2010. The game has also been released as part of Jakks Pacific's TV game controllers. Hamster Corporation re-released the arcade version as part of their Arcade Archives series for the Nintendo Switch and PlayStation 4 in August 2023.
