"As for Zeus and Isaac, Iím very happy to announce they will come to North America FREE as a redeemable downloadable voucher code packed in with the new God of War: Ascension, which launches on March 12th. When Zeus and Isaac Clarke go live in All-Stars on March 19th (one week later), you can use your code to redeem them any time after they are live. For anybody who doesnít pick up God of War: Ascension (but of course thatís only crazy peopleĖitís got what I think is the most epic final battle in the seriesí history), the characters will also be for sale in the PSN Store for $4.99 each."
