Microsoft is planning to effectively double the amount of campaign content available for Ninja Gaiden 2.

25 new missions are set to be released for the game. As Microsoft puts it, that's "equivalent to a whole new campaign mode".

The content will be available from July 25th at 800 Microsoft Points.

Microsoft tells us, "You’ll easily get to grips with Survival based missions, though it won’t be easy fending off enemies with only one type of weapon to master. More focus is required in Karma Attack missions, in which you are aiming for the highest scores possible."

SPOnG can't help but wonder if the devs over at Team Ninja have even been allowed to sleep over the last few months, or if sneaky Ninpo magic has been worked on them to turn their eyes red and make their fingers bleed as they prepare all that new content.
