Fox Engine
Hideo Kojima stood at the end of a long road after finishing Metal Gear Solid 4 in 2008. He looked forward to building something entirely new for his studio, Kojima Productions. The goal was simple yet ambitious: create what he called the best engine in the world. This tool would allow his team to develop games across multiple platforms without spending years on production cycles. Before this moment, the studio had focused heavily on single-platform development. Kojima wanted to break that pattern and streamline how his team worked. He named the project Fox Engine, drawing inspiration from FOX, a fictional military unit within the Metal Gear series. The name also reflected the company's own logo, which featured a fox emblem taken directly from that same fictional universe.
Konami took the stage at E3 2011 to show off early capabilities of their new technology. A demo played out inside a jungle environment where a young man ran freely through the area. A horse and a dog moved alongside him as part of the test scene. This footage did not represent a game ready for release but rather served as a development sandbox. Assets used in the demo came directly from work-in-progress materials for Metal Gear Solid V: The Phantom Pain. On the 17th of August 2011, Hideo Kojima posted facial rendering tests on Twitter for public viewing. Later that year during a lecture at the University of Southern California, he showed students a forest scene created with the engine. By December 16, more images appeared online including one demonstrating cloth transparency effects. These releases built anticipation while keeping actual gameplay details hidden from fans.
On the 14th of March 2013, Joakim Mogren appeared on GameTrailers TV holding an iPad displaying screenshots of a mysterious project called The Phantom Pain. The Fox Engine logo sat quietly in the bottom right corner of each image shown during the interview. When host Geoff Keighley pointed out the logo and asked why it was there, Mogren became visibly nervous before the conversation abruptly ended. Many gaming websites suspected the entire segment had been staged by Konami to gauge reactions without revealing too much. Three weeks later on the 27th of March 2013, the truth emerged: The Phantom Pain was actually Metal Gear Solid V. Moby Dick Studio and its head Joakim Mogren were fictional entities created solely for this marketing stunt. Kojima explained that presenting the game as unrelated to the Metal Gear franchise allowed them to observe genuine public response to the engine's visual capabilities before official announcements.
Pro Evolution Soccer 2014 launched in 2013 as the first commercial title powered by the Fox Engine. It appeared simultaneously on Microsoft Windows, PlayStation 3, and Xbox 360 systems. This release marked a turning point after years of development work began following Metal Gear Solid 4. Over the next seven years, the engine supported multiple entries in the Pro Evolution Soccer series including versions released in 2015 through 2019. Other titles like Metal Gear Solid V: Ground Zeroes arrived in 2014 across five different platforms. P.T., a survival horror experience exclusive to PlayStation 4, also utilized the technology during its brief run. By 2018, Metal Gear Survive joined the list of games built with the same underlying framework. Each new release demonstrated how the engine could handle diverse genres while maintaining consistent performance standards.
After seven years of continuous use across various sports simulations, Konami decided to stop developing with the Fox Engine entirely. The decision came as PES Productions shifted focus toward next-generation hardware including PlayStation 5 and Xbox Series X consoles. Unreal Engine replaced the proprietary tool as the preferred choice for future projects. This transition reflected changing industry demands and technical limitations faced when targeting newer systems. The discontinuation ended an era that had begun shortly after Hideo Kojima completed his previous major project in 2008. No further updates or support were planned for existing users of the discontinued software. The shift signaled a broader strategic change within Konami regarding how they approached game development moving forward into the late 2010s and beyond.
