As the 20th anniversary of Blizzard’s popular Diablo franchise approaches, all other major titles prepare to celebrate with an exclusive demon-themed event.

This year marks the 20th anniversary of Blizzard’s long-running franchise Diablo and, to celebrate the occasion, the company is releasing a host of special in-game events in some of its other currently active titles.

Blizzard fans are in for a treat, as a large amount of Diablo-themed bonus content will be showing up in fan-favorite games very soon. Diablo III will be receiving an in-game event named “The Darkening of Tristram,” allowing players to run through a re-imagined version of the cathedral present in the original Diablo.
