Ninja Gaiden 2 is getting it’s first expansion this week with the addition of Mission Mode for 800 MS Points. The pack contains 25 stand-alone stages not found in the story to test your skills.

There are two types of missions for the new stages. Karma Attack is there to see how high you can raise your score. Survival gives you one weapon and throws endless enemies at you until you die. Both are cool additions for $10.

To go along with the Mission Mode pack, there are now 30 videos on the Xbox Live Marketplace that show off the locations of all the crystal skulls. Don’t worry, these videos are free.

If Ninja Gaiden is your thing and the camera didn’t make you almost puke like me, grab the pack and let us know your thoughts.
