Wow, there's a reason to consider buying the Blu-ray of the Total Recall remake! If you purchase the "Director's Cut" Blu-ray, or the Blu-ray/DVD combo pack, you'll get the E3 demo of God of War: Ascension. The Blu-ray, and the God of War demo, arrive December 18. The demo is exclusive "through 3/8/13," suggesting that a demo will hit PSN four days before the March 12 launch.
God of War demos and sci-fi movie Blu-rays have been mashed together before. Back in 2009, Sony tossed a God of War 3 demo in with District 9 on Blu-ray.
