means i can got it in this way ?
Step 1: Play Catherine on PS3 while connected to PlayStation Network.
Step 2: Acquire at least one Gold Prize in the game's Golden Theater mode on normal difficulty setting. This will unlock Babel Mode's Altar stage.
Step 3: Clear the Altar stage in 7 minutes for a bronze prize avatar, 6 minutes for a silver prize avatar and 5 minutes for a gold prize avatar.
Step 4: Profit! The avatar will be sent to your PS3 message box within two weeks of the campaign's end. If you don't get it... don't e-mail me because I have no idea what you should do.
I doubt that it matters at this point. The promotion was announced more than a year ago. I doubt that it is still available anywhere now, even if it was available worldwide in February of last year. I can't find any details of the campaign. but the use of the term suggests that you had a limited time to accomplish the challenge; which would have ended a long time ago.
There is no mention of the avatar on the US Catherine game site. That would suggest that either the avatar is no longer available in the US, or that it never was available in the US. It may have been Japan only (I don't read Japanese, so I can't check the Japanese Catherine site), but I certainly would not plan on getting it with a US account at this point.
