Civilization VI was recently updated to give Windows and Mac players cross-platform multiplayer, sadly the Linux version was left out. We spoke to Aspyr to confirm what's happening.
It's not just cross-platform multiplayer that we're missing, as the Linux version hasn't recieved the Spring 2018 Update yet which was released for Windows back in May. Sadly, this type of wait has become common when a third party ports a game to Linux and it's understandably hard for some to have to wait—especially if it's a game you're particularly fond of and one that can be enjoyed in a multiplayer environment.
The good news, is that Aspyr Media are obviously well aware of this. Here's what they told us today:
We are very close to getting both the update and cross platform play out on Linux. If all goes well, we should see both in the next couple of weeks.Aspyr Media
