Blizzard’s Diablo series has its 20th anniversary this year, and Blizzard is going hard to celebrate. Not only will Diablo III have some celebrating, but their other big titles including Heroes of the Storm, Hearthstone, Overwatch, StarCraft II, and World of Warcraft will have in-game celebrations.


As for Diablo III, it will have an in-game event called The Darkening of Tristram, which allows players to run through an updated version of the cathedral from the first Diablo. Overwatch and Heroes of the Storm are offering Diablo-themed rewards, and Hearthstone will have a “hooded stranger” coming to the battlefield.

“As we approach the original game’s release anniversary on December 31, Blizzard Entertainment is thrilled to commemorate twenty years of Diablo,” the company wrote in their announcement, “We’re ready to celebrate our passion for the world of Sanctuary and the brave heroes who inhabit it!”

Below are Blizzard’s descriptions for each game’s celebrations:
