Treyarch is spreading holiday cheer today with the start of another double XP weekend in Call of Duty: Black Ops 4.

The latest double XP weekend is now live, starting today (Friday, Dec. 28) at 12pm CT. Double XP and double weapon XP will be available in multiplayer and Zombies, as well as double Merits in Blackout, Black Ops 4's battle royale mode.

The double XP weekend is set to end at 12pm CT on Jan. 1. But Treyarch could always decide to extend this double XP period even further to celebrate the start of 2019 in style.
