Microsoft plans to release a new downloadable mode for Ninja Gaiden 2 on 25th July.
This is Mission Mode and it has 25 different mini-challenge stages to aim for high scores on. These will be a mixture of using different weapons or staying alive as long as possible as well as lots of other rules and regulations.
Your scores will be fed into leaderboards so your friends can see them and be coaxed into besting them. The Mission Mode challenge bundle will cost 800 Microsoft Points (GBP 6.80 / EUR 9.60).
Also, available tomorrow will be 30 videos explaining where all of the skulls in the action slasher are. Which is nice.
