Killzone Shadow Fall sales pass 2.1 million
Sony has announced global Killzone Shadow Fall sales of over 2.1 million.
That accounts for both physical retail "sell-in quantities" and digital PlayStation Store sales combined, as of January 15, 2014.
With Sony having claimed 4.2 million PS4 sales by the end of 2013, this would indicate that almost half of all PS4 owners have picked up a copy of the Guerrilla Games first-person shooter.
