That is actually not live-action, but in-engine.
It is using brand-new technology that scans real world enviornments in 3D.

Eschewing the usual clichés and gung-ho settings currently inhabiting the FPS genre, Get Even subtlety removes the classic division between single-player and multiplayer experiences to unfold two linked stories. The game's plot revolves around the memories of its central heroes which have a dramatic effect on how the game progresses.
To create the photo-realistic visuals that bring the gritty universe to life, Get Even is the first game to use large-scale, real-world scanning to create expansive and lifelike environments. This 3D scanning technology combines with advanced lighting effects to create a stunning and believable world that pushes the boundaries of the genre.
You'll also be able to be any random NPC in the Campaigns of your friends at any time.
