Jeff Minter (born 22 April 1962) is an English video game designer and programmer who often goes by the nickname Yak. He co-founded independent video game developer Llamasoft in 1982 and was the sole game designer and programmer until Ivan Zorzin started being co-credited in 2008. Minter has created dozens of games, starting in 1981 for the ZX80, then later the ZX Spectrum, VIC-20, Commodore 64, Atari 8-bit computers, Amiga, Atari ST, Jaguar, and other systems. A majority of Minter's projects are shoot 'em ups, often based on games from the golden age of arcade video games such as Defender, Tempest, and Robotron: 2084. Minter has evolved a game design style which combines psychedelic visuals, references to ruminants (especially llamas, sheep, and camels), and quirky audio samples.
Minter's works include Gridrunner (1982) and Tempest 2000 (1994), both of which he has revisited and expanded into new releases multiple times, Attack of the Mutant Camels (1983), and Polybius (2017). He developed a series of music visualization programs, beginning with Psychedelia in 1984 and culminating in Neon, which is built into the Xbox 360 console. In 2011–2013, Minter and Zorzin released nine games for iOS, inspired by 1980s computers and video game consoles, under the banner The Minotaur Project. Many Llamasoft games are self-published, but Minter has also had games released by Human Engineered Software, multiple incarnations of Atari, and other publishers. Many of his games are collected in Llamasoft: The Jeff Minter Story released in 2024 for Windows and consoles.
Pre-commercial career (early years)
Minter began programming computers at a young age. He wrote the game Deflex for the Commodore PET in 1979. However it would not be until a long illness during a university year that Minter's talents would develop in any meaningful way. Following a three-month stint due to a sudden eruption of pericarditis, in which Minter was restricted to lying on his back and was confined to his bed between November 1981 and January 1982, boredom led him to take up computer programming in earnest to pass the time. Upon recovery, Minter teamed up with Richard Jones, a fellow pupil, and together they started writing their own games on their school's PET. They soon parted ways. Jones went on to co-found Interceptor Micros.
In 1981 Minter started independently writing and selling video games for the ZX80, the first machine he owned. Some were made for software company dk'tronics. These titles were sold as a package but this was not available for very long, as Minter left the company following a royalties dispute. He formed a partnership with his mother, Hazel Minter. Together they developed and commercially produced 20 games for the ZX81, VIC-20, Atari 8-bit computers, ZX Spectrum, and Commodore 64. Having been studying physics at the University of East Anglia, success in the programming industry prompted him to drop his studies and take up video game development full-time.
The following year, he founded the software house Llamasoft. His first Llamasoft game was a Defender clone for the VIC-20 called Andes Attack (US version: Aggressor). In Andes Attack, the player had to protect llamas instead of the humanoids from Defender. As a fan of Defender, Minter would remake it again as Defender 2000. Through the Brighton-based software house, Salamander Software, Minter had his games written for the Spectrum and other home microcomputers. It was Mr S.A. Tenquist who was responsible for the ZX Spectrum 16K version of Gridrunner. The conversion was released and published for Christmas 1983 by Quicksilva Ltd., UK. Jeff Minter's original Commodore version was written in a week and marked his first commercial success both in the UK and in the US.
Minter went on to develop a number of games for the Commodore 64, Atari 8-bit computers, and Atari ST which were marketed by word of mouth and magazine advertisements. These included Gridrunner, Abductor, Matrix: Gridrunner 2, Hellgate, Hover Bovver, Attack of the Mutant Camels, Revenge of the Mutant Camels, Return of the Mutant Camels, Laser Zone, Mama Llama, Metagalactic Llamas Battle at the Edge of Time, Sheep in Space, Voidrunner, and Iridis Alpha.
In 1989, Minter helped in the production of the Konix Multisystem console.
Minter worked for Atari Corporation and VM Labs. For Atari he produced Tempest 2000 (1994) on the Jaguar. It was a remake of Dave Theurer's 1981 Tempest. He followed it with Defender 2000 (1995) on the Jaguar, a remake of the 1981 arcade game. Listing Minter in their "75 Most Important People in the Games Industry of 1995", Next Generation called him the Jaguar's "leading developer". Minter also produced the Virtual Light Machine (VLM-1) for the Jaguar CD add-on. For VM Labs he created the VLM-2 and Tempest 3000.
Minter then wrote games for the Pocket PC platform, some of which also have Windows conversions: Deflex, Hover Bovver 2: Grand Theft Flymo (a reinterpretation of his own 1984 game, Hover Bovver), and Gridrunner++.
In 2002, he began work on a music video game for the GameCube to be called Unity. Using the newest version of his VLM, the VLM-3 or Neon, Unity was to combine the two main threads of Minter's prior career: light synthesis and classic arcade style shooting. Minter was involved in writing this game for Lionhead Studios throughout 2003. The project was cancelled in December 2004. Neon has since been reprogrammed and significantly expanded and is used in Xbox 360 media visualisation.
In 2007 Minter released Space Giraffe, an action video game with similarities to Tempest. Space Giraffe was released for Xbox 360 through Xbox Live Arcade.
In 2008 it was announced at the Tokyo Game Show that designers at Llamasoft were working on the visualisation aspects of the Xbox 360 version of Space Invaders Extreme. The game was released in 2008. In December 2008 Space Giraffe was released for Windows.
In September 2009 he released Gridrunner Revolution for Windows as a digital download.
In 2010, frustrated with the delays surrounding the release of his titles, Minter was keen to return to a style of game development where games could be produced and released quickly. The iOS platform was chosen and Llamasoft announced that a series of games would be produced under the banner The Minotaur Project. The idea behind the series is that Llamasoft would develop a game in the style of a past computer or console but without the constraints of the original hardware.
On 5 January 2011 he released Minotaur Rescue for iPhone 3GS, iPhone 4, iPod Touch (3rd generation), iPod Touch (4th generation), and iPad.
On 2 March 2011 Llamasoft released their second iOS game, Minotron: 2112. Minotron: 2112 is a remake of the Atari ST / Amiga game Llamatron (which was inspired by the coin-op video game Robotron: 2084). An iOS version of Deflex was also released although this was not specifically labeled as being part of the Minotaur Project.
On 17 September 2011, Llamasoft released GoatUp, their first platform game.
