Ninja Gaiden II DLC this week

The first batch of downloadable content for Ninja Gaiden II has been revealed by Microsoft, a pack that includes an 800 Microsoft Point 'Mission Mode' bundle and some videos.

The Mission Mode includes 25 self-contained survival stages, featuring trials not found in the normal, single-player, story.

Karma Attack missions give you the challenge of obtaining the highest score, while Survival missions do what they say on the tin: try not to die using only a single weapon as waves of enemies rush you.

There are also 30 free videos included (in three packs) that reveal the locations of the hidden skulls in the main game.
