While Monster Hunter Rise has a lot of classic elements, there's some new goodies in there as well. That includes the Wirebug, which is a new way of getting around and fighting. In an internal Capcom interview, Producer Ryozo Tsujimoto talks about why players should take the time to learn the ins and outs of the Wirebug.
It’s a completely new feature, so it’ll take some time to get used to, but you don’t need to whisk around the map right from the start, and we made sure the game is fun enough without using the Wirebug. ...If you manage to incorporate your Wirebug into your combos, your repertoire of moves will expand significantly, but what that means is that you’ll just have even more choice on top of the already rich amount of strategy you normally have.
