The video shows Mario exploring a brand new area with Bowser Jr. at his side, and Bowser's looking bigger and badder than ever before. At times, Bowser's Fury appears to offer up a beautifully bright region to explore with all the charm and colour you'd expect from a new Nintendo adventure, but there's also a much darker side to the new content, as we're about to see.
Let's start things off with the cutesy, happy stuff. Just look at Plessie – that adorable plesiosaur could make even the darkest of times just that little bit brighter.
Nice, right? Yeah, well forget all that, because things are about to get serious. We can't remember seeing Bowser look quite this scary before, and we like it.
If you're keen to grab a copy ahead of the game's launch next month, Super Mario 3D World + Bowser's Fury pre-orders are now live. A new Mario-themed Switch console was also announced today to coincide with the game's launch next month.
It's looking pretty good, huh? Feel free to share your thoughts in the comments below.
