We're not far now from the official release of Gears 5 worldwide, but unfortunately players in China are going to be waiting longer, it seems, as The Coalition have stated a 'specific issue' is preventing access to the game in the region.
The company released a statement explaining that sales and pre-orders have been suspended in China due to an unforeseen issue, although it didn't give any specifics into what the issue actually is, so it's unclear if it's technical or political in nature.
There is a specific issue with the Gears 5 release in China preventing people from accessing the complete game. Unfortunately, this issue means we have to suspend future sales and pre-orders, as well as the game’s release, in China at this time, we are investigating and will provide an update once we have more information. We appreciate your understanding.
There are some rumours floating around that the issue relates to matchmaking and server overload issues, but this has not been confirmed. Given that these issues are only just cropping up now, before release but after beta testing, makes this unlikely to me, though.
Given the country in question, it could also be a censorship or other political issue, which may also explain the lack of specifics about what is causing this delay.
Stay tuned to GameFront for more on this as we learn it.
