The Type-1 Whirlwind is a pistol manufactured by Hellstorm. A dedicated support weapon, the Whirlwind makes up for its poor damage ability and pierce with a generous clip size and an ability to slow the movement of zombies. Although it does not affect large zombies and bosses very effectively, it is invaluable for slowing Runners and Stalkers to allow for teammates to mow them down with greater ease.
