Diablo IV is set to receive "meaty" quarterly updates every three months: updates that will introduce new storylines, according to Game Informer.

In Game Informer's latest cover story, Diablo IV associate game director Joe Piepiora said that while he hesitates to use the word "expansion," the game's post-launch quarterly updates will consist of additional story content that will be tied into the new mechanics and features of each update. Updates will additionally be accompanied by a new seasonal battle pass, which will come in both free and premium forms. Blizzard has previously confirmed that the game's first season will not go live with Diablo IV and will come sometime later.

Blizzard recently offered more information on what exactly Diablo IV's endgame will look like in the form of a developer video. Nightmare dungeons, alongside areas out in the open world called Helltides, will make up the bulk of the endgame experience. Nightmare dungeons serve as harder, remixed versions of the more than 100 dungeons present in Diablo IV at launch, with various affixes further spicing up the replayability of each dungeon.
