The story
Arika was founded in November 1995. During the first month of its existence, the company was focused strictly on research.
In July 2011, a video from an Arika 3DS test project, called Fighting Sample, was released, featuring Hokuto and Kairi from the Street Fighter EX series. Further screenshots were released, showing characters Blair, Doctrine Dark and Shadow Geist, but the project was later cancelled. Later in May 2016, another video showcasing Nanase, Allen, Darun and Skullomania was released as a sample test video, with no plans for a future release. In April 2017, Fighting EX Layer, which seems to be the "evolution" of Fighting Sample was announced as a video for April Fools, and later confirmed to be actually a game in development. Fighting EX Layer is a spiritual successor to both Street Fighter EX series and Fighting Layer, an arcade-only fighting game by Arika.
Tetris: The Grand Master 4: Masters of Round has been shown to be in development multiple times since as early as 2009. However, it was cancelled later on due to various reasons, including copyright infringements with regard to emulation and various fan-developed clones of TGM, most notably Texmaster2009. The Grand Master 2015 was announced and playtested in both Japan and the United States in June 2015. This playtest was not licensed by The Tetris Company. In late 2024, Arika officially announced Tetris: The Grandmaster 4: Absolute Eye, scheduled for March 2025.
Not long after completion, a Tetris the Absolute: The Grand Master 2 PLUS port to the PlayStation 2 was shown to be in development. However, for unknown reasons, the port was not licensed and was never released.
Arika collaborated with Bandai Namco Entertainment to help co-develop Tekken 8. This collaboration also lead to it handling update patch(es) on Tekken 7.
