Get Chains of Olympus free with a PSP from Gamestop By Patrick Garratt, Monday, 18 May 2009 20:48 GMT Share on: Facebook Twitter Reddit Google+ Gamestop’s offering God of War: Chains of Olympus free with PSP purchases at the moment. Bargain. Especially as Sony’s about to announce PSP-4000 at E3. Rumour, obviously. But it is. Thanks, Joystiq.
