This might come as a surprise, but there's a lot of discrimination in the ninja industry, or the "ninjustry" as those of us in the 'biz call it.

Ninjas have all the cool gadgets and powers. They have a seemingly limitless array of grapple hooks, shuriken, and the physical strength to use them.

Bowja's latest adventure won't take long to complete, but you'll enjoy the ride while you're there.

Final Ninja is a side-scrolling action/adventure with plenty of ninja-goodness like wall-jumping, stealth mode and rope grappling.
