Galaga

 is a 1981 fixed shooter arcade game developed and published by Namco. In North America, it was released by Midway Manufacturing. It is the sequel to "Galaxian" (1979), Namco's first major video game hit in arcades. Controlling a starship, the player is tasked with destroying the Galaga forces in each stage while avoiding enemies and projectiles. Some enemies can capture a player's ship via a tractor beam, which can be rescued to transform the player into a “dual fighter” with additional firepower.
Shigeru Yokoyama led development with a small team. Initial planning took about two months to finish. Originally developed for the Namco Galaxian arcade board, it was instead shifted to a new system as suggested by Namco's Research and Development division. Inspiration for the dual fighter mechanic was taken from a film that Yokoyama had seen prior to development, where a ship was captured using a large circular beam. The project became immensely popular around the company, with Namco's president Masaya Nakamura even taking interest.
Although early location tests proved unsuccessful, "Galaga" received critical acclaim, and is one of the most-successful arcade games. It is widely regarded as a classic of the golden age of arcade video games and one of the greatest video games of all time. Critics applauded its gameplay, innovation, addictive nature and improvements made over its predecessor. Several home ports were released for a multitude of platforms, including the MSX, Atari 7800 and Nintendo Entertainment System, alongside releases on digital distribution platforms such as Xbox Live Arcade. "Galaga" is also included in many Namco compilations. It was followed by a sequel in 1984, "Gaplus".
Gameplay.
"Galaga" is a fixed shooter. The player mans a lone starfighter at the bottom of the screen, which must prevent the Galaga forces from destroying all of mankind. The objective of each stage is to defeat all of the Galaga aliens, which will fly into formation from the top and sides of the screen. Similar to "Galaxian", aliens will dive towards the player while shooting down projectiles; colliding with either projectiles or aliens will result in a life being lost.
Atop the enemy formation are four large aliens known as the "Boss Galaga", which take two shots to destroy. These aliens can use a tractor beam to capture the player's ship, returning with it to the top of the formation and costing the player a life. Should additional lives remain, the player has an opportunity to shoot down the Boss Galaga holding the captured ship. Shooting it down as it dives towards the player will result in the captured ship being rescued, and it will join the player's ship, transforming it into a "dual-fighter" with additional firepower and a larger hitbox. However, destroying a Boss Galaga with a captured ship while it is in formation will instead cause the fighter to turn against the player and act as an alien.
Some enemies can morph into new enemy types with different attack patterns, with one even taking the form of the Galaxian Flagship. Stages are indicated by emblems located at the bottom-right of the screen. Enemies become more aggressive as the game progresses, increasing their number of projectiles and diving down at a faster rate. The third stage and every fourth thereafter is a bonus stage, where the aliens fly in a preset formation without firing at the player.
Development.
"Galaga" was created by Japanese developer Shigeru Yokoyama, a long-time veteran of Namco. Namco's first big hit in arcades was "Galaxian" (1979), credited as one of the first video games to use RGB color graphics; the game's success led Namco to produce a large number of Namco Galaxian arcade boards to keep up with demand. 
By the early 1980s the game was becoming harder to sell, so to help clear out inventory, Yokoyama was tasked with creating two new games that could run on the Namco Galaxian board. The first of these was "King & Balloon" (1980), a fixed shooter that is cited as the first video game to incorporate speech. The second game was instead made for newer hardware as suggested by Namco's Research & Development division. This new arcade board was named the Namco Galaga, and used in games including "Bosconian" (1981) and "Dig Dug" (1982). Although Yokoyama was not given explicit instructions to make a shooting game, management expressed desire for him to make a game similar to "Galaxian". Initial planning for the project took two months.
The idea for the dual fighter stemmed from Yokoyama wanting to create enemies with different attack styles. The tractor beam emitted by the Boss Galaga was inspired by a film in which a character's ship was captured by a circling laser. Yokoyama incorporated this idea into "Galaga", whereby an enemy could capture the player's ship with a beam and the ship would need to be rescued. Originally, rescuing a captured ship would award the player an extra life, but this was soon changed to having it fight alongside the player. This idea proved to be a problem at first; due to hardware limitations, the game could only display a limited number of sprites, resulting in the dual-fighter being unable to shoot any more missiles. As a workaround, Yokoyama made a 16x16 sprite for the ship and a 16x16 sprite for the bullets, reducing the total sprite count by two.
Inspired by the intermissions in "Pac-Man" (1980) and bonus stages in "Rally-X" (1980), Yokoyama added a special bonus level. While planning, lead programmer Tetsu Ogawa informed him of a bug whereby enemies would simply fly off the screen instead of moving into formation. Ogawa expressed interest in incorporating the idea into the game, leading to the inclusion of the Challenging Stages. Enemies originally flew in one type of pattern, with more being added to increase replay value. Graphic designer Hiroshi Ono designed many of the sprites, including the player's ship and the Boss Galaga alien.
Prior to location testing, the team focused on designing the instruction card, a sheet of paper that showed how the game was played. The text was done by the planners, while the actual design was handled by a graphic artist. The card originally showed the control layout and the basics of the game, which was stripped early on for being too boring. Yokoyama suggested that the card instead show off the dual fighter mechanic, as a means to draw in players. The team kept bringing in designs to Namco president Masaya Nakamura, who continued to reject them until he ordered the team to simply make it in front of him.
The team was allowed to set their own deadlines, due to Namco's then-laidback corporate structure. Feedback on the project was given by Nakamura and other employees, including "Pac-Man" creator Toru Iwatani. Despite the game's immense popularity around the company, early location tests failed to meet expectations due to players being able to progress a long way with only one coin, thus generating low income. Although Yokoyama stated that the game's popularity could still generate income, Namco executives instructed the team to increase the difficulty level. "Galaga" was released in Japan in September 1981. It was released in North America by Midway Games in October of that year.
