During the surprise Nintendo Direct Mini this morning, Nintendo announced that Super Mario Odyssey is receiving a free update in February with new items and opportunities to compete with other players online.
Once the update is released, players who have completed the story mode can look forward to Balloon World, which you enter by talking to Luigi atop a skyscraper in New Donk City. Balloon World lets you hide balloons within stages that other players must race to find, and conversely, you can compete while racing to find other balloons hidden by players from across the globe--everyone's performances are ranked online.
The update will also introduce three new costumes: a Super Mario Sunshine-themed shirt and glasses, a musician costume, and a full set of knight armor. Lastly, new snapshot filters for the photo mode will also come with the update, including one that lets you create your own gold-tinted Mario coin pic.
Super Mario Odyssey earned a 10 from us late last year, and GameSpot voted it the third best game of 2017. It was a great year for Nintendo overall, with Switch becoming the fastest selling console in the US, and Super Mario Odyssey taking the top slot of Amazon's best-selling games of the year.
