Enix was a Japanese video game publishing company founded in September 1975 by Yasuhiro Fukushima.
 Initially a tabloid publisher named Eidansha Boshu Service Center, it was renamed to Enix in 1982, and shortly thereafter ventured into video game publishing for Japanese home computers such as the PC-8800 series, the X1 series, and the FM-7.
 Enix initially found games to release by holding contests for programming hobbyists and publishing the winners, with the first titles appearing in February 1983.
 Enix continued to hold contests and publish the winners through 1993.
 When Enix moved into traditional publishing for video game consoles in 1985, it began with ports of two of its more successful games, "Door Door" (1983) and "The Portopia Serial Murder Case" (1983).
 From that point onward, Enix served as a publisher for both video games developed independently by other companies as well as for titles in franchises owned by Enix and created by licensed developers.
 Enix's flagship franchise was the "Dragon Quest" series of console games, developed primarily by Chunsoft; some of the games, such as "Dragon Quest VII" (2000), have sold millions of copies, and the series as a whole has sold over 68 million copies as of 2016.

Maverick Hunter is the codename for a cancelled first-person shooter video game in the "Mega Man" franchise that would have been developed by Armature Studio and published by Capcom.
 It was intended to be a darker entry in the "Mega Man X" series.

 The game would have had similar platform elements found in earlier "Mega Man X" titles.
 It had a lifespan of about six months in 2010 before it was ultimately cancelled due to the aforementioned internal disagreements around the same time as Inafune departed from Capcom and other "Mega Man" titles were cancelled.
