Konami also produced its shoot 'em up arcade games such as Gradius, Life Force, Time Pilot, Gyruss, Parodius, Axelay, and TwinBee. Konami's games based on cartoon licenses, especially the Batman: The Animated Series, Teenage Mutant Ninja Turtles Animaniacs and Tiny Toon Adventures series, but other American productions like The Simpsons, Bucky O'Hare, G.I. Joe, X-Men and The Goonies and French comic Asterixall have seen release at some point in the past by Konami either on arcades and/or video game consoles. Recent cinematically styled franchises from Konami are the continuing Silent Hill survival horror franchise, and the Metal Gear series, which underwent a public renaissance with Metal Gear Solid. Another successful franchise is Winning Eleven, the spiritual sequel to International Superstar Soccer, which is extremely popular in Asia, Latin America, Middle East and Europe, where it is sold by the name Pro Evolution Soccer.

However, use of this code in more recent Konami productions has been sparse. The company was widely criticised for distributing the PC retail release of Metal Gear Solid V: The Phantom Pain with a disc containing an 8 MBSteam installer, leaving the player to download the 28 GB of game content.

Founded in 1998 by Vadim Khrulyev, CEO, KraiSoft Entertainment had quickly become a solid team of software engineers, writers, artists and musicians consolidated by the idea of bringing cutting-edge computer entertainment to life. Four years of corporate evolution followed which made a valuable result: three best-selling game releases, a number of freeware products and two major projects closing to its completion. Along with a huge experience gained in online distribution, we've now entered into negotiations with several major software publishers in order to start retail distribution of our products. We also got our games published on lots of compilation CDs (including upcoming Activision Great Games compilation) and computer magazine cover-CDs. There are genres in computer entertainment development that are traditionally considered as too "light" and "hollow". Such a depreciation leads to a terrible result: there are lots of truly brilliant game ideas with a truly awful realization. Players get tons of junk instead ones of gold. It must be corrected, and we're here to do this. We take good ideas and turn it into brilliant games - no mater the genre, each good game idea deserves implementation with supreme technologies involved. And we add as much technology as it takes to produce some truly stunning entertainment.

Kronos Digital Entertainment was an American video game developer founded by Stan Liu in 1992. They first began to develop original properties, beginning with their visually appealing early 3D fighting games, Criticom, Dark Rift and Cardinal Syn (referred to as the "Trilogy of Terror" by one gaming journalist).  The organization later gained greater critical and commercial success for the Fear Effectseries with Eidos, although Kronos retains all rights to the franchise. Kronos was busy developing the third installment in that series, Fear Effect Inferno, when publisher Eidos discontinued funding for the project following a major restructuring of their budget. The developer then shopped it around to other publishers but were unable to secure another deal to get the game finished. The company disbanded soon after, with Fear Effect 2: Retro Helix being their final released game.

Kuju Ltd is an international video game developer. Kuju was formed in 1998 in Shalford, Surrey, England, after a management buyout of Simis from Eidos Interactive. Kuju has released titles across different devices, ranging from Art Academy on the Nintendo DS, The Lord of the Rings: Aragorn's Quest for the Wii, and an Xbox One title, Powerstar Golf. The name "Kuju" originates from the initials of the founders’ first names: Ian Baverstock and Jonathan Newth. Jonathan was leafing through a Japanese dictionary when he found the numbers nine and ten – "ku" and "ju" – corresponding to the positions of "I" and "J" in the English alphabet. The combined result was Kuju. In 1998, Ian Baverstock and Jonathan Newth were running Simis, an in-house development studio owned by Eidos. In the same year, Ian and Jonathan led a management buyout of the studio from Eidos Interactive, forming Kuju Ltd. Their first game was Tank Racer – a 3D action racer for PC, PlayStation and Mobile. By 2001, Kuju was employing a team of 80 developers, in three separate offices around the UK in London, Surrey and Brighton. Their most notable project at the time was Microsoft Train Simulator. In 2002, Kuju floated on the Alternative Investments Market (AIM) of the London Stock Exchange. Shortly thereafter the company signed its first game with THQ based on the Games Workshop franchise – Warhammer 40,000: Fire Warrior. In the following years between 2002 and 2007, Kuju developed titles including SingStar games and the Battalion Wars franchise. In 2007, Kuju Ltd. was acquired by a German media investment firm, Catalis SE. Soon after, Kuju Brighton was rebranded to Zoë Mode, and in 2008, Kuju London rebranded to Headstrong Games. In 2010, Headstrong Games completed development of Art Academy for the Nintendo DS console. In 2012, Dominic Wheatley of Domark was appointed as CEO.
