You won't have to spring for new games to take advantage of the Xbox One X's 4K prowess. Microsoft is updating several of its own games to play in 4K on the newer console. In addition to the already-announced Minecraft upgrade, you can expect to see the higher resolution in Gears of War 4, Forza Horizon 3, Killer Instinct and Halo Wars 2 (what, no Halo 5?), among others. Unsurprisingly, all of the updates will be free -- Microsoft wants there to be as many One X-ready titles as possible.
