A new game coming from Metal Gear creator Hideo Kojima will show off the new Fox Engine. This next-gen, multiplatform game engine was revealed in Konami's pre-E3 announcements today. Kojima says that this engine will be the future of Kojima Production games, and that it will let them move away from developing games made for a single platform. This new game, which may or may not have been shown in the presentation, will most likely not be a Metal Gear game. Don't cry.
The demonstration ran on an Xbox 360 dev kit. It featured a guy moving through a highly detailed jungle, where super-realistic leaves fall in the background. Also shown: A super shiny and muscular dog and horse. It's not much, but GameTrailers has a good look at what little there is.
Here's the important part: The next game from Kojima Productions will use this fancy new Fox Engine. We know this game will be multiplatform and will be created for a global audience.
