There has been a relative dearth of solid sports titles from Nintendo in recent years, meaning we must savor every last morsel of that which is available, namely Mario Tennis Aces for the Nintendo Switch.

Like many of Nintendo's recent sports titles, Mario Tennis Aces thrives in online play.  In order to keep this competitive mode from getting too stale, Nintendo seems to have settled on a slow but steady drip of new characters, each with their own attributes and playstyles.

Version 2.0 of Mario Tennis Aces drops today and brings with it the first of many limited time co-op challenges that you can take on with friends in order to unlock new outfits and new color schemes for the in-game characters. The current challenge is titled "Boo Hunt" and is available starting today until Thursday, October 11.
