Here’s two interesting things to note about Dead Rising 2: Case Zero — classified “zombie paradise action” — in Japan.
1. It costs 200 Microsoft Points more than its English counterpart.
2. It’s a CERO Z game.
And by extension of being a CERO Z game — Japan’s very first digital CERO Z game, in fact — it can only be purchased with the use of a credit card. No credit card means no purchase, because that’s how Microsoft are trying to verify people are 18 and above before letting them download the game.
