Ninja Gaiden 2 - Secret Achievements (Xbox 360)

Ninja Gaiden is one of the most successful games on the Xbox 360 and the sequel will probably outsell the latest titles. Ninja Gaiden 2 will feature a new and improved engine, redeveloped from the ground up exclusively for the Xbox 360 by Team Ninja, with the help of Tomonobu Itagaki, the creator of the Dead or Alive series.

The story follows Ryu Hayabusa on a mission to avenge his clan's name and to prevent the end of the human race. He only has his ninja training and weapons to complete this tremendous task, and there is not a creature in the world that can stop him from doing so. One of the most important modifications brought to the original game is the possibility to record Ryu's exploits and share his greatest achievements with the Xbox Live Community.

If you want to know exactly what those achievements are, then check out the list below.
