'Diablo Immortal' has been delayed suddenly in China.
Blizzard's free-to-play mobile and PC action role-playing game was due to launch on June 23 in the region, but just three days prior to the release date, a notice on China's 'Diablo' website explained that there are several reasons for the setback, including "a number of experience, network and performance optimisation" issues which need improving.
The statement read: “We are sorry to inform you that Diablo: Immortal’s scheduled launch on June 23rd will be delayed.
“The development team is working on a number of optimisations to the game – greater device support for a wider range of models, maximum graphics quality on more models, a number of experience, network and performance optimisations and more.
“We believe that the game experience will be smoother in the official launch version, bringing you better game content.”
A new release date is yet to be confirmed.
Meanwhile, Blizzard recently declared that the game achieved the "biggest launch in franchise history".

The official Diablo Twitter page tweeted: "Shoutout to the heroes of Sanctuary.
