Fox Engine

The Fox Engine is a proprietary cross-platform, cross-generational game engine built by Kojima Productions for use in many Konami games. The engine's development began after the completion of 2008's Metal Gear Solid 4, with the goal of making the "best engine in the world." The engine makes it possible for Kojima Productions to develop multiplatform games with a significantly shortened development time and has been described as the first step for the developer to move away from development for a single platform. The engine is named after FOX, a fictional military unit from the Metal Gear series, wherein is also a reflection of Kojima Productions itself, which based its company logo on FOX's fox emblem.
