Every Extend is series of puzzle shoot 'em up video games primarily developed by Q Entertainment. The series began with a 2004 freeware game of the same name (also known as E2) for Windows, which was a personal project by Kanta Matsuhisa under the "Omega" pseudonym.[1] Q Entertainment discovered the game online and approached Matshisa to develop a remix version. The remix version was developed for the PlayStation Portable and was released in 2006, titled Every Extend Extra (or E3). In 2007, Q Entertainment developed and released a sequel on the Xbox 360 titled Every Extend Extra Extreme (or E4).
