You start off in a white room with white floors and white walls and a white ceiling. Everything is white, and you might not even realize that you’re in control at all until you start pressing buttons on the controller. Tap forward and you’ll hear footsteps, move and you’ll notice an aiming reticule dart across the screen. Press a shoulder button and you’ll lob a blob of black paint, which splatters into the environment, giving shape to the shapeless. Then, and only then, does the world around you begin to form and become navigable.
