Green Ninja: Underworld app for iPhone and iPad
Although you have mastered all the ninja skills,
Underworld is more dangerous than you think.
So, let me give you a tip!
Jump and dodge are the two most basic ninja skills - always be prepared to use them to survive!
If you fight strong Boss Monster, lure attacks first and youll get a perfect chance to make a counterattack.
Remember that, when fighting monsters, you yourself are the Green Ninja!
And youre not alone if you play with your ninja friends, too.
Good luck!
