Nintendo has announced Arms for Switch, a fighting game that combines boxing and shooting, where you use extendable arms to battle. It will launch this spring.
To play Arms, you hold both Joycon controllers up. When you punch, your character punches. When you twist your fist, your punch curves. By performing dashes and jumps, you can perform a variety of actions.
Because the game uses physical controls, anyone can pick it up and play it right away. It will support both local and online multiplayer.
