special event in Akihabara later this month (June 20th) will promote the still-unreleased God of War: Chains of Olympus, and those in attendance will be able to get this special keychain. In addition, artist YOU THE ROCK will make an appearance.
Although the God of War franchise is incredibly successful in America and Europe, it hasn't managed to break through in Japan. God of War II managed to sell about 40k units total on PS2. While PSP is quite the hot system in Japan right now, it's unclear how the Japanese populace will respond to this incredible, but American-developed, game.
