Sony announced early this month that it had purchased Guerrilla Games, the developer of the Killzone FPS series. While financial details were not disclosed, the companies shared a very close working relationship following the signing of an exclusivity contract in Spring 2004. In the announcement, Sony Computer Entertainment Worldwide Studios president Phil Harrison said Guerilla Games has a “great combination of creative, technical and production talent in their team and we have enjoyed a close working relationship with their management and staff for a number of years.” The latest installment of the Killzone series is currently in development for PlayStation 3 by Guerrilla Games.
