Fist

The fist is the player's stock melee attack. It is always available unless the player has picked up a chainsaw. Punching is only about as effective as a pistol shot, however, unless the player has collected a berserk powerup, which increases the power of the fists tenfold. Like the pistol, the punch is used via left hand. The Doom Marine is credited to know and wield Sosaiken " The Art of the Dragon " of Billy&Jimmy Lee in Double Dragon, honorary of their characterized inspiration and comparision to the Doomguy.
