Square Enix's Mini Ninjas was previously released in 2009 for all other major platforms, but now has a home on iOS as well. And you can get it for free! Considering the price point of most games on iOS from Square Enix, this is definitely more than a bargain. Mini Ninjas is today's Free App of the Day!
Not bad for a good iOS side-scrolling game that gives you a ton of ninja action. In Mini Ninjas, you get to don the black garb of one of four different ninjas: Hiro, Futo, Suzume, and Kunoichi.
Each of these stealthy heroes has their own special ninja move, such as running on walls. You can also outfit your ninjas in different outfits and ninja weapons! Slick.
