The first-person shooter genre is defined by its seminal moments. There's Doom's corridors. There's Quake's multiplayer modes. There's Tribes' breadth and scale. There's Modern Warfare's online progression. And now, there's Battlefield 4's levolution. Sure, the name is awful and its creator should be shot. But the idea--taking of an online multiplayer level, and through player action, fundamentally altering that level--will be the new industry standard for the biggest and most lucrative genre in gaming. That fact alone puts Battlefield 4 at the top of this list of the best Xbox One games.
