Face it, everything is better with ninjas. It's like in that movie The Last Samurai when all the ninjas attacked. It was like, "Whoa, ninjas! This movie just got even awesomer!" Imagine that feeling, only applied to Castle Crashers. See, it feels awesome, righ?. The game was already cool and now it has a ninja and is even cooler (and by cool we mean totally sweet). If you thought it couldn't get any better than that, then get this: the ninja carries ... a mug. Not just any mug ... a Ninja Mug. We're not quite sure how it works, but according to the Castle Crashers website, its purpose is "defensive shielding."
It's official now: the wait for Castle Crashers is killing us. Follow the source link for shots of ninja doing his thing.
