Grand Theft Auto V is celebrating the holidays, and today GTA Online got a wintry makeover. In the latest GTA Online update, San Andreas has received a blanket of snow, there are free liveries and a free car coming on Christmas, and a new vehicle is now available for purchase.

As part of GTA V's Festive Surprise event on PS4, Xbox One, and PC, San Andreas is now covered in snow. What's more, you can throw snowballs at people. By hitting left on the d-pad or G on your keyboard, you can pick up a snowball and then throw it at NPCs or your friends.
