Prior to the release of Resistance 3, Sony released the first dual pack. This pack included the first two games, Resistance 2 DLC and a special skin for Resistance 3. Shortly after another was released for Uncharted, which included both games and a vast amount of DLC. Since then the packs have ended, but it seems Amazon has listed another two packs.
The first pack is for inFAMOUS, which will include both games and ideally the DLC for 2 or Festival of Blood. As far as the second pack, it is for the God of War Saga. However the details around this one are up in the up. The pack will most likely include 1 – 3, but it could be a dual pack of the collections. Beyond this nothing more is known, but these are sure to be a great value to new comers or people waiting to pick up these titles.
