This week's Xbox Live deal involves ninjas so naturally we're interested. Microsoft has cut the price of the Mission Mode DLC pack for Ninja Gaiden II by 33%.

You can now buy the Mission Mode pack for 560 Microsoft Points instead of the usual 800 Microsoft Points. As with all these Xbox Live deals, you'll need to have an Xbox Live Gold premium subscription in order to be eligible.

The Mission Mode DLC was released back in July and adds 25 new missions. It also includes ten new Achievements. Ninja Gaiden II hit stores last June exclusively for the 360.
