Though it wasn't immediately clear whether Rise of the Tomb Raider would be coming to the Windows Store when it arrives on PC in January, that indeed appears to be the case. The official Windows Store Twitter account announced that Rise of the Tomb Raider will be "coming soon" to the Windows Store. And given that the game is due to arrive for Windows 10 PCs via Steam next month, we wouldn't expect its Windows Store arrival to be too far off.
The news also raises questions if Rise of the Tomb Raider is the first Project Centennial game e.g. a Win32 port to the Windows Store or something else. Project Centennial was announced back at Build as a way to bring classic Windows apps and games to the new Windows 10 Store (they can even be larger than 150GB in size). However, since the announcement, not much news has come out about the Bridge technology.
Rise of the Tomb Raider was originally released as an exclusive title for the Xbox One and Xbox 360 in November, but the exclusivity period is almost up, heralding the game's impending arrival to other platforms.
Similar to Steam, buying Rise of the Tomb Raider through the Windows Store will enable one-click installation or removal, along with automatic updates.
