Dubbed “Overwatch’s Winter Wonderland,” the latest major update for Blizzard’s gigantic hero shooter sees the battlefields and characters of Overwatch get a little more festive for the holidays.

A new arcade game mode, which sees teams of six facing off in snowball death-matches, plus two winter map variants, and another 100 cosmetic offerings (with associated loot boxes) to round out the winter festivities. Learning from a promotional event for the Olympic Summer Games, players can buy any seasonal cosmetics they choose via in-game currency, and with various ways to earn loot boxes that don’t involve purely team-based games, Blizzard is at least learning while updating Overwatch.

The Winter Wonderland event runs from now until January 2nd, 2017.
