Following the sequel announcement at The Game Awards, speculation immediately arose regarding the game engine for the Ōkami sequel. IGN exclusively confirms that Capcom's RE Engine will power the game, based on interviews with key project leads.
Machine Head Works producer Kiyohiko Sakata confirmed the use of RE Engine, highlighting their role as a bridge between Capcom (IP holder and director) and Clover (development lead). Sakata emphasized Machine Head Works' experience working with Capcom, understanding their needs, and prior collaboration with director Hideki Kamiya. Crucially, they possess expertise in RE Engine, a skillset lacking within Clover's development team. Furthermore, Machine Head Works includes personnel with experience on the original Ōkami, providing additional support.
Capcom producer Yoshiaki Hirabayashi succinctly stated that RE Engine was essential, explaining that without it, Kamiya's artistic vision wouldn't be achievable. Kamiya himself added that RE Engine's renowned expressive capabilities align with the anticipated quality for this sequel.
Sakata further teased the potential of RE Engine, suggesting it allows the team to realize aspects of the original Ōkami's vision that were previously unattainable. He believes current technology, coupled with RE Engine, will surpass their past ambitions.
RE Engine, Capcom's proprietary engine (originally for Resident Evil 7), has powered major titles like the Resident Evil series, Monster Hunter, Street Fighter, and Dragon's Dogma. While most RE Engine games feature realistic art styles, the application to Ōkami's distinct aesthetic presents exciting possibilities. Capcom's development of the REX engine, a successor gradually integrating into RE Engine, may also contribute to the sequel.
