At the Metal Gear 25th Anniversary event Kojima Productions demoed their rumoured Fox Engine project titled “Metal Gear Solid: Ground Zeroes”.

Although photos of the event could not be taken,  from Twitter state that the presentation included a real-time cutscene that went over into gameplay. The demo showcased an open world level with Snake taking out guards, evading search lights and riding around in a jeep. Supposedly, the game was running on a PC.

At this time, it cannot be said if the demo was actually part of the final product or if it was a mere tech demo, as Kojima Productions has presented gameplay segments in the past that were not included in their actual titles in development.
