Nearly half of all PS4 owners bought Killzone: Shadow Fall

Perhaps the most high-profile release of the PS4 launch was Killzone: Shadow Fall. Guerrilla Games' shooter is arguably one of the prettiest games on the console, one that serves as a technical showpiece for next-gen. Unsurprisingly, it's sold pretty well, with Sony announcing sales of 2.1 million units worldwide.

With Sony most recently announcing sales of 4.2 million consoles, that means nearly half of all PS4 owners purchased the game.
