Thirst Level: 5.25

Where do you think Solid Snake got his watchful eyes from? There are multiple moments in MGS3: Snake Eater, where you're able to view Eva "Big Mama" Tatyana's beautiful body, through the eyes (halfway through the game it becomes eye) of Big Boss himself. And at the end of it all, in complete James Bond fashion, Big Boss finally gets what he wanted. Operation Thirst Quencher, completed.
