Snake: Reactive armor, huh? Otacon: That's right, Snake. The material you're wearing is a mechanical neural network -- meaning there's no computer chips or other SPOF (single point of failure). The material itself is smart, the fabric is doing the thinking as a whole, responding to the environment to protect you from incoming fire. Snake: I don't like the feeling of wearing something intelligent. Otacon: Just think of it as like an alien symbiote costume, like the heroes from those old tokusatsu shows wore. Snake: You're not helping.
