The M133 is a pump-action shotgun with a shorter barrel that disperses buckshot in a wider pattern. It excels at clearing out rooms and hits hard close up.

The M133 is the first shotgun that players can unlock in the game, and while it doesn't measure up to the others, it is still effective at taking out enemies at close range. It is unlocked for free in shops after activating 5 Radio Towers.
