When we were first introduced to the Xbox One, we heard about the hardware. Today, at Microsoft's E3 keynote, it was all about the games. We had a look at Metal Gear Solid V: The Phantom Pain, a One-exclusive Killer Instinct reboot, and Ryse: Son of Rome (both an exclusive and a launch title). We also learned that Minecraft would be getting some expanded multiplayer options when it hits the new console, and checked out the "open-world shooter" Sunset Overdrive. That wasn't all: we caught some stunning footage of Forza Motorsport 5, as well as Quantum Break (exclusive), Crimson Dragon, The Witcher 3, and zombie survival game Dead Rising 3 (arriving "this holiday" as a One exclusive). We saw some hectic action in Battlefield 4, which will have a "Second Assault" DLC available to Xbox One users first, and spied Titanfall, another exclusive landing "spring 2014." You can also make your own games, of course, and there are a bunch of trailers available now at the source link, including some for titles not shown off on stage. Oh, we almost forgot to mention. New Halo.
