Whether you plan to play Gears of War 4 on Xbox One or PC, Microsoft and The Coalition have a few maintenance-related boxes you need to tick if you want to dive right in when the game launches on October 11.
PC owners have the most hoops to jump through. You can now pre-order Gears of War 4 through the Microsoft Store and pre-load the game, but The Coalition wrote a forum post explaining that you'll need to download the Windows 10 Anniversary Update for the game to work. The update has been available since August 2, so you probably already have it. To double check, click Start à Settings à Update & security à Check for updates.
Additionally, make sure to grab the latest Windows update, KB3194496, released just yesterday, September 29. Versions previous to this recent update sporadically caused downloads to restart.
Xbox One owners who have their sights set on a disc-based edition of Gears of War 4 will have to wait just a bit longer than everyone else to get fragging. A day-one update must be download before playing.
