From the crew that brought us the 'Amateur Surgeon' comes the all new 'Amateur Ninja'! You play as Willow Stiletto on a quest to save your Sensei and fellow ninjas from the evil Megacorp! Great looking (Amateur Surgeon graphics) stealth game from adult swim. The Level 1 descriptions sets things up nicely "Sneaking in through the back door is totally ninja. You quest for vengeance starts here!"...
