Ground Zeroes showcases Kojima Productions' FOX Engine, a true next-generation game engine which promises to revolutionize the Metal Gear Solid experience. The first Metal Gear Solid title to offer open world gameplay. Ground Zeroes offers total freedom of play: how missions are undertaken is entirely down to the user. Unrestricted stealth: Imagine classic Metal Gear gameplay but with no restrictions or boundaries. Players use intelligence and cerebral strategy to sneak their way through entire missions, or go in all guns blazing. Each will have different effects on game consequences and advancement. Multiple missions and tasks - Ground Zeroes boasts a central story mode and Side-Ops missions ranging from tactical action, aerial assaults and "covert" missions that will be sure to surprise. Ground Zeroes users will benefit from a clean in-game HUD that shows the minimal amount of on-screen data to give a more intense gaming experience.
