Sony is promoting inFamous in Japan with a God of War 3 demo coupon. Japanese gamers can get their hands on the demo by redeeming the code on the PlayStation Store. The demo will be available to download from November 19th 2009 until February 2010. Unfortunately, there was no mention if the demo would also be available in the West.
The God of War 3 demo will, however, be included in the God of War Blu-Ray collection when it launches. Each copy of God of War Collection will include a voucher code that can be redeemed through PlayStation Network on the day of purchase.
