It's a ninja fighting game, using taijutsu, ninjustu, genjutsu, etc, to beat the opponent. You can have up to two support characters to fight alongside with. I like it because there are so many characters with different attack styles.
I could add one. I don't really like the way the fandom twists and turns ponies and over thinks them.
I'm not active anymore but it used to bother me. Ultimately that is why I quit mostly.
