Best Buy is looking to do just that with a PS4 launch game sale and is offering up Knack and Killzone: Shadow Fall for $40, with free shipping on all orders over $25.
Best Buy is also knocking some ducats off Call of Duty: Ghosts, Battlefield 4 (both the Standard and Limited editions) and Injustice: Gods Among Us Ultimate Edition. All of these games are available for $50 with free shipping.
While we'd have a hard time suggesting Knack for any price, Killzone: Shadow Fall is a tempting deal. In our review, we said Killzone: Shadow Fall has some interesting sci-fi moments but is ultimately a game residing on "the border between good and great."
