Snowballs

"Be on the lookout and ready to round up your Crew for a friendly snowball fight, but be forewarned, those icy little suckers can pack a wallop."

- Rockstar Games

Snowballs are a temporary weapon featured in Grand Theft Auto Online during the Festive Surprise.

Description
Snowballs can be gathered and stored three at a time by pressing D-pad Left when a player is unarmed in snowy weather. Nine Snowballs can be stored at a time and will disappear when swapping sessions or starting Jobs.

Snowballs are thrown using the same animations as Grenades and can therefore also be tossed underarm. Hitting a pedestrian's head with a snowball will knock them down, but they will stand back up. Two snowballs to the face can be sufficient to kill a pedestrian. On some surfaces, where a snowball is thrown, it will leave a powdery texture (e.g. on vehicles). Snowballs can also smash vehicle headlights.

Trivia

 * They are one of the few weapons that are only present in GTA Online
