Nintendo seems keen to address Arms' overall thin initial offerings in terms of stages, characters and modes. Since launch the game has been updated a handful of times to add more, and today brings another. Arms 4.0 adds Misango, a man with robotic scorpions for fists. Yes, really. He also has a mask that can help guard against facial damage. There's also a new stage that Misango calls home, and you can see that in the trailer embedded below. Nintendo hasn't updated the fighter overview page online just yet -- or the patch notes -- so it isn't clear what else Misango will bring with him.
