Today in Tokyo, Konami showed off its brand new Fox Engine with a demonstration. The engine's demo ran footage of something called Metal Gear Solid: Ground Zeroes.

The thing is, this is not just a tech demo. This is an upcoming, new, open-world Metal Gear Solid game.
"This announcement is a challenge from Kojima Productions to the world," said Hideo Kojima.

The footage showed off how the engine can handle weather (like rain) as well as clothing textures and lighting.

In the demo, Snake crawled to avoid some searchlights. After a quick stealth kill, he hopped in a jeep and called in a helicopter for evac. The concept behind Ground Zeroes is that this is a "Game without Game Over".

So even if a player is discovered in this stealth title, the game isn't about to end. Instead, it's just getting started. Here, it sounds like Kojima Productions is adding a new spin to the sneaking genre—a genre the developer is a master of—by making more of a game out of the escape itself and allowing players to do things like radio in for support. The demo seemed to indicate that Ground Zeroes wants players to do much more than simply run and hide.

"Sounds like MG, but the scale & atmosphere... Wow," tweeted game localizer Mark MacDonald of 8-4.

The demo was running on a PC at current-gen specs, and its wow-factor seemed to impress those in attendance. It's also been designed with the Xbox 360 and PS3 in mind.

The Fox Engine, however, isn't only for current gen. Konami is positioning the Fox Engine for both Cloud gaming and next gen consoles. -Kotaku
