According to a Reddit thread, a leaked Target flyer features a very interesting deal for November 15th a.k.a. PS4 launch day. The flyer states if you buy two launch games for the PS4 you get the third one free. Yes, that is correct, free.
The games listed on the flyer are Assassin’s Creed 4: Black Flag, Battlefield 4, Fifa 14, Madden 25, NBA 2k14, Killzone: Shadow Fall andKnack. Additionally, the flyer states “more available in-store”, so it’s probably safe to assume more titles will be eligible that day.
Of course this is all still very speculative until the actual official flyer from Target comes out. Until then, we can hope right?
