It's finally time for Snake to take on the giant electrical dude known as Volgin, and though it's kinda anti-climactic considering it's the last face-to-face engagement you have with him, it's still a solidly entertaining boss fight. There's not much more to this than just unloading every bullet in your inventory and avoiding his widely-telegraphed electrical attacks (unless you want to take down his stamina, which just requires CQC and tranqing instead), with much of the tension deriving from the 5-minute time limit the battle has. It's fun to see Ocelot and Volgin arguing mid-battle, but like the Snake/Liquid fight atop Metal Gear REX, it's just a little too simplistic and straightforward for the final mano-y-mano showdown between the hero and the antagonist (excluding The Boss, because, you know). Granted, both had extra fights afterwards, but there's nothing quite like a one-on-one, close quarters punch-up.
