When it comes to an authentic ninja gaming experience, no one can beat Klei Entertainment. Its side-scrolling action/adventure Mark of the Ninja, which came out last year for digital download, did an awesome job when it came to using sneaky capabilities and killing enemies with honor.  

Next week, you'll be able to use these skills again, as the developer has new content coming. The "Special Edition" DLC for Mark of the Ninja features an all-new level, as well as two additional items for use, a costume for your main character, and according to Klei's Twitter account, a "whole lot of developer commentary."

The content will sell for $4.99 (400 Microsoft points) and arrives on both Xbox Live Marketplace and Steam August 16th. If you haven't checked out the game yet, we recommend doing so. It never hurts to brush up on your ninja skills.

Mark of the Ninja is out now for Xbox Live Arcade and Steam.
