Organizers of the second round of the Master Ninja Tournament on Xbox Live have decided to extend the registration period for the Ninja Gaiden competition. Players will now be able to sign up through next week. The tournament, in which competitors play through the game with the new content and post their karma scores on Xbox Live, will begin August 9 instead of August 2. It will conclude August 30.Unfortunately, the extension also means that new Hurricane Pack: Volume 1 expansion content won't be available until August 9. The Hurricane Pack will add stronger enemies, better camera controls, and the new Boujutsu weapon to Tecmo's acclaimed action game. Players can learn more at the tournament's official Web site.
