Tecmo will release a Ninja Gaiden Sigma 2 demo in North America next week, but you don’t have to wait to play it. You can get the demo right now with a Japanese PlayStation Network account.
Logon to Japan’s PlayStation Store, select the menu option with “PV”, and then pick the icon with Ryu’s face to download the demo. That’s all the Japanese you need to wade through since the Ninja Gaiden Sigma 2 demo is in English.
Initially, Ryu is the only available character. After you complete Ryu’s stage, which ends with a fight against a giant stone Buddha, you can try out Ayane. The final game includes two more characters, Rachel and Momiji, and comes out in North America on September 29.
