During a Metal Gear 25th Anniversary panel at PAX 2012, designer Hideo Kojima talked about the development of the Fox Engine
, which powers Metal Gear Solid: Ground Zeroes
. Kojima spoke briefly about the engine's potential and versatility.
"The thing is, once we get the Fox engine moving as we do now. You can make an FPS, you can make an Uncharted, etc. But what I wanted to do is make an open-world game, and that's what I'm doing now," he said.
Kojima added that "other Konami studios may use it as well," and gave the Silent Hill series as an example.
