Open-world Metal Gear Solid: Ground Zeroes revealed

In conjunction with the 25th anniversary of the Metal Gear series, Kojima Productions and Konami announced the first open-world game in the franchise, the Fox engine-driven Metal Gear Solid: Ground Zeroes, which attempts to take the series beyond its traditional stealth roots.

Dubbed as a Game without Game Over, the concept is that even if Snake is discovered, there are plenty of options for the hero to get out alive, evolving the series to be more than just a sneak fest. The demo showed Snake (no prefix) sneaking and killing on a huge military base, then driving a jeep and calling for a helicopter to pick him up, Kotaku said.

The new Fox engine, which apparently did a superb job with atmospheric effects such as rain, lighting and shadows, was running on a PC with series creator Hideo Kojima using an Xbox 360 controller for the action. According to GameSpot, Kojima said the engine is designed for next gen consoles, but the game has been designed with Xbox 360 and PS3 in mind. No platforms or release date were officially announced.

Konami also announced the first social game in the series, Metal Gear Social Ops, developed by Gree using the Unity engine. According to Andriasang, players will be able to "relive the stories" of their past Metal Gear exploits using cards for battle. The game is expected to be released later this year.
