Earlier today Hideo Kojima revealed Metal Gear Solid: Ground Zeroes.
The new game is thought to be an open world entry in the franchise featuring real-time cutscenes powered by Kojima Productions' new Fox Engine.
While Kojima presented a gameplay demo running on PC and played with an Xbox 360 controller, no filming was allowed, so you'll have to wait a little longer to see it in action.
But according to GameSpot the gameplay demo took place in a remote, rainy military base. It showed the protagonist entering a prone state to sneak around before switching to a third person aiming mode to shoot a guard at a security checkpoint.
The site also reports: "The demo gave out a sandbox open-world vibe; the military base itself felt expansive and huge, and Snake can summon a helicopter to bring him around as well as drive a jeep to go from point A to B."
Metal Gear Solid Ground Zeroes was announced this morning at a Metal Gear Solid 25th Anniversary event, where Kojima also revealed Metal Gear Solid: Social Ops, a social game inspired by Portable Ops and Peace Walker.
A Metal Gear Solid movie is also in the works, with X-Men and Spider-Man producer Avi Arad attached to the project.
