The Age of Empires developers have a holiday surprise for everyone. It’s an official Yuletide graphics asset Winter Celebration mod for Age of Empires II: Definitive Edition. It’s a free in-game download that will turn the ground snowy, change spears into candy canes, and snowballs become weapons of mass destruction. You have until sometime in January to download it, at which point the team will remove the mod from the listing. Once you have it, you can enable it from within the game and play in winter whenever you want.
