Ninjas. They're all stealth and shadow and subterfuge, sure. But that doesn't mean they don't have All-Stars within their midst. But how do you find out which is the most all-starriest of the ninja all-stars? Well, you could play Ninja All-Stars from Ninja Division. It's available now.
The game is heavily favored toward league play, with a community-driven emphasis. Players create their teams, then over the course of a season, build up their team's skills and ratings as they finish various missions. Each clan has their own strengths and paths to greatness, emphasizing different skill sets.
As I mentioned, you can pick up the game at your local retailer or through the Ninja Division webshop.
