Inferno Island guide: how to beat Boom Boom in Mario Tennis Aces

Once you reach Inferno Island, you’ll face Boom Boom in a level called Mechakoopa Crisis. This level is infuriating, but like most of the Adventure mode in Mario Tennis Aces, there’s a trick which makes it fairly trivial to beat.

During each point, mechakoopas will start to appear from pipes on the side of the court, slowly walk towards you, and once near enough, will start to explode.

You might have noticed by now that you can hit the mechakoopas over the net with charged shots, but this is a red herring. You’ll be busy enough returning Boom Boom’s shots to do this with any level of consistency, and once there’s multiple mechakoopas on the court, it’s just a matter of time until you get hit by an explosion and lose the point.

So here’s the trick – Boom Boom cannot block special shots. He starts with four rackets, but if you focus on charging up your shots, there’s more than enough time during the match to build up your meter enough for four special shots in order to get the K.O.
