The snow is back in GTA 5 with the latest holiday update.
In order to pick up snow, you’ll need to have your hands free. In other words, you must be holding just your first. Then press left on your D-pad. This will let you pick up 3 snowballs at a time, for a total of 9.
To throw the snowballs, just aim and shoot like you would any gun or grenade. Keep in mind, much like a dreaded iceball, these snowballs can actually kill people in the game.
