Gamefly‘s monthly sale has begun on used stuff, and it gives you some massive savings on next-gen stuff. Next gen deals include Need For Speed Rivals at $25, LEGO Marvel Super Heroes for $25, Knack for $25, and the biggest bargain in the form of Killzone: Shadow Fall for $20. Last-gen deals include Assassin’s Creed III for $8, AC IV: Black Flag for $18, and both Brotherhood and Revelations for $10. Batman: Arkham Origins is $18, while Battlefield 4 and Call of Duty: Ghosts are only $18 as well. Saints Row IV is a mere $13. The newest bargain is Yaiba: Ninja Gaiden Z at only $20. That game has gotten mixed reviews, but I personally loved my time with it. If you want a really stylish action-heavy brawler, pick it up.
