Have Some 'New' Screenshots
Hideo Kojima has confirmed that open-world stealth 'em up Metal Gear Solid: Ground Zeroes will feature a dynamic day/night cycle that actively affects the world itself. Enemies, patrol routes and other variables will change depending on the time of day, making your choice of when to infiltrate as important as how you do it. There will also be loading scenes to break up different zones, if that's important to you. [Eurogamer]
Kojima Productions has also released some 'new' screenshots, which are quite obviously grabbed from the Ground Zeroes reveal trailer. You can marvel at the Fox Engine after the break.
