When I first played Contra 3, I had a blast. But when I got to the skeleton boss I had to change my underwear. Seeing those giant claws rip through the metal doors like paper was really frightening. Plus the frantic nature of the fight made my adrenaline pop a few dozen times. With it's eye beams that chase you around the room, and his fire breath that is nearly impossible to dodge. Oh, don't forget the bombs he throws into the room that give you two seconds to get to a safe corner. If you can beat him without getting a continue, then you are a god!
