Diablo 4 experienced one of the biggest updates since its launch in 2023 with the release of it Vessel of Hate DLC and Season 6 content. From a new class known as Spiritborn to enemies called Realmwalkers, fresh content in the Diablo 4 brings more action to the fore. However, when it comes to the Infernal Hordes mode, players trying to enjoy couch co-op have encountered a major bug that prevents them from completing runs.
Despite the influx of new content season 6 and Vessel of Hate bring, couch kaap Diablo 4 faced a series of setbacks. Another issue arose last month when players realized that the Dark Citadel raid DLC did not support couch co-op. Players attempting to experience Infernal Hordes using this method are now stuck mid-game with no clear way out.

A nasty bug makes the infernal hordes a real pain
At this point, it seems like this issue with Infernal Hordes is mostly a couch co-op issue. The wave-based mode can be a fun way to counter the onslaught of enemies, but unfortunately for couch co-op, players can't seem to pass the test. A Reddit user known as MaidenlessRube expressed his frustration on Diablo 4 subreddit, claiming that this issue occurs regularly when attempting the mode in local co-op. New waves will stop spawning, leaving players in a mode with no way forward. This isn't Infernal Hordes' first problem either.

Constant bugs that prevent players from completing objectives
A similar bug that previously affected players in Infernal Hordes is related to the mode's end goal. Once the wave of enemies reaches the final stage, players will be tasked with destroying the Fell Council. However, according to feedback posted on Blizzard's official forum on the company's website, some players have defeated the Fell Council, but nothing happens and they can't continue.
While not quite the couch co-op bug plaguing players, it was still a shockingly similar software lockout issue that may prevent some from fully playing Infernal Hordes. Player Allisonk98 said on Reddit that the software lockout “occurs so often I hardly ever play.” Diablo 4 got a recent patch but it didn't change anything about the Infernal Hordes problem.

Blizzard has yet to fix this issue
As of this writing, Blizzard has no known plan to address Infernal Hordes' local co-op issues. While the developer has responded to Spiritborn's awesome gameplay, players who want to experience Infernal Hordes with another player may have to wait a little longer for the issue to be resolved. What's even more frustrating for players is how long this problem has been going on. According to MaidenlessRube, “this has already happened since the beginning of Season 5.”

A recent patch made changes to the Obducite game crash issue and improved servers and stability.
It is not known how long this problem will remain with couch co-op players. Unfortunately, as it recently turned out that the majority Diablo 4 players are solo, this may not be a priority for Blizzard at this time. Only time will tell if this bug will be fixed soon, but for those looking to try out Infernal Hordes in local co-op, it may be best to proceed with caution.
