Amazing, just amazing !
The gameplay of Snake Eater is similar to that of previous games in the Metal Gear Solid series. Snake, controlled by the player, must move undetected through a hostile, enemy-filled environment. Although Snake acquires various weapons (ranging from handguns to rocket propelled grenades), the emphasis is on using stealth to avoid confrontations. A number of objects and gadgets can be found along the way to aid in this, including motion detectors[18] to track hostile soldiers, and the Metal Gear series' trademark cardboard box, which Snake can hide under to avoid visual detection.
Despite the fundamental similarities, Snake Eater introduces many new aspects of gameplay not present in previous Metal Gear games, including camouflage, a new hand-to-hand combat system called "close-quarters combat" or "CQC", a stamina gauge, and an injury-and-treatment system.
