Metal Gear Online, the competitive component of Metal Gear Solid V: The Phantom Pain (aside from base invasion stuff), will get an opt-in beta today on PC.
Those details were announced through the Metal Gear Solid V Steam community hub by Robert Peeler; (presumably) one of the few people left at Konami working on this series.
“Players can opt in and download the Beta release of Metal Gear Online January 12th, 10PM PT,” the post reads. At the time of writing, that’s in another half hour or so. [Edit]: No it isn’t, I mistook PM for AM. It’s in another 10 hours.
However, the same announcement adds that “that’s our target time, there’s a chance it’ll slip by an hour or two as we implement this awaited update, but rest assure we will be here for support and launch as planned.”
When it becomes available, it will probably appear as an opt-in drop-down menu found under the game’s Beta tab (found by right-clicking on MGSV in your Steam library, navigating to properties, and then locating the beta section). Alternatively, it may show up as a separate download in the libraries of those who own MGSV. Most likely the former, though.
Metal Gear Online was released for the console versions of the game last year, with the PC release scheduled for January. Looks like they’re on course for that.
