Here’s Mark of the Ninja, A Stealth-Action Sidescroller

Klei Entertainment, developers of the Shank games, are working on a new stealth-action sidescroller, Mark of the Ninja. They announced the game today for Xbox Live Arcade, along with a trailer which you can watch below:

On the game’s website is a short (but very neat) text-adventure game you can play. If you make the right choices and manage to get to the end, the trailer above gets “unlocked” for watching. It’s a cute way to promote the game, and the text does a nice job of conveying a certain mood.

Mark of the Ninja is slated for release this summer on Xbox Live Arcade.
