Success posted a demo of Raiden Fighters Aces sitting on the Japanese Xbox Live Marketplace. If you have Gold account activated in Japan you can grab it now. Otherwise you have to wait until next week to blast ships with a curved laser when it becomes publicly available.
At this point it is unclear if the demo will be region locked like the Operation Darkness demo Success released last year. Hopefully, the digital download and the DVD which comes out on March 27 won’t.
