Nintendo Switch sales are already up to 10 million, and that's not including all those extra units sold at Christmas.

If you're a new Nintendo Switch owner, then Express Online has picked out a selection of must-have extras for you to buy in the sales.

Arguably the most important of the lot is a carry case, which lets you make the most out of the console's portability factor.

You'll also want a screen protector to stop your console from picking up scratches, and additional chargers are useful for keeping your Switch powered up on the move.

A second Joy-Con is also ideal, while Pro Controllers are perfect for gaming ports like Doom.

And it looks like 2018 could be an even better year for the Nintendo Switch.

It was recently revealed that the original Bayonetta and its sequel Bayonetta 2 are coming to Switch next year.

This new bundle will be available on Nintendo Switch from February 16.

And that's not all, because Bayonetta 3 is also coming to Nintendo Switch at a later date.

Capcom, meanwhile, has announced plans to release Mega Man 11 on Nintendo Switch next year.

Likewise, Mega Man Legacy Collection and Mega Man Legacy Collection 2 are being released on Nintendo Switch in Spring 2018.

The Nintendo Switch will also host Bridge Constructor Portal, which is a spinoff of the popular Valve games.

"Bridge Constructor Portal will blend the laws of structural engineering and technology straight from Aperture Laboratories into an exciting new game experience, all under the demanding gaze of GLaDOS.

"If you've been paying attention the solution should be obvious. As the case may be... good luck!"
