Fist

The fist is the most basic weapon in Doom. Punching is almost useless unless the player has collected a berserk pack.
 * 1) With berserk pack

The actual punch attack is started two frames into the punch animation. The fist is not completely extended at this point, but considering this can help in timing punches effectively.

In original Doom, if a player has a chainsaw, they cannot switch back to fists unless they have a berserk pack.

With berserk powerup, the power of the fists is increased tenfold.
