The new concepts initially introduced in the game via last year's E3 are Snake's outside environment and his abilities to survive and stealthily progress through said rough terrain. He uses camouflage to hide, stalk, and kill his enemies, whether that means hiding in the grass, high up in trees limbs, below the water surface, or by blending into the jungle itself. Using the environment to attack and to survive are also key new concepts that shape the game's new design. Snake can hang from trees with one hand and shoot from his other hand; he can drop down from tree branches to break enemy necks, and he can climb them to snipe enemies as well. In short, all of Snake's high-level military techniques are now being attributed to an outside environment, rather than an indoor one.
