Did Blizzard sneak a secret post-credit scene in Diablo 4?

As to what the scene itself entails, it isn't an elaborate spectacle but rather a brief, ambiguous tease. A demon appears for a few seconds against a backdrop of hellish red, its face pulsating ominously before vanishing. There's no dialogue at all or any context, only the visage of a demon with no clear identity.

Some say it's reminiscent of Diablo, which would make sense since his name is still on the title but others believe that it's Mephisto. After all, the Lord of Hatred offered his help to players throughout the single-player campaign of Diablo 4.

In any case, the game offers no explicit confirmation, leading players to theorize that this could be part of what Blizzard is teasing when it promised that it had big plans for Diablo 4 ahead of the release of the first season in mid-to-late July.

However, amidst the wave of speculation, confusion has arisen over the criteria for triggering the post-credits scene. Some players have suggested it might be tied to the game's difficulty, while others have reported seeing it only after multiple playthroughs. Some players, despite finishing the game and sitting through the credits, have not witnessed the scene at all. Blanco, too, appears uncertain about the conditions that lead to its triggering, promising to investigate this within Blizzard.

This peculiar post-credits tease is reminiscent of the long-standing tradition of the gaming community's love for secrets and Easter eggs. Blizzard, in particular, is still believed to have snuck in a Secret Cow Level in Diablo 4, despite saying numerous times that it doesn't exist in the game - yet.

While the definitive identity of the fiery demon remains an enigma, the debate rages on in the gaming community, with theories ranging from the return of Diablo to the emergence of new villains. One thing is certain: the anticipation for the first post-launch season has been stoked to a fever pitch. In the coming weeks, as Blizzard begins teasing their upcoming content, we may start to see some sense emerge from this infernal mystery. Until then, all we can do is speculate, theorize and, just like Blizzard boss, Mike Ybarra, keep on playing.
