Bah. If they were fighting in the real world, Neo's supah-1337 matrix god powers would be useless. And he would probably try to use MP5K's akimbo or a certain weapon with magazines belonging to another, different, certain weapon.
*Neo enters battle arena with a MP5K and Uzi in his hands. Looks around for Snake. Suddenly, drops dead from bullet shot. Snake steps out of darkness with a supressed SOCOM pistol, with a cig sticking out of his mouth. Snake then mouths a cool line, and the battle is over.*
