Nintendo also announced it is working on Metroid Prime 4 for the Switch.
When is Metroid: Samus Returns coming out?
Nintendo announced that the game will be out on 15 September 2017.
We reviewed the game, awarding it 4/5 - read the review here.
How much will it cost?
The game costs £34.99 in the UK in line with most other major 3DS releases.
What is the style of gameplay?
The game is a remake of the 1991 Game Boy game Metroid II. As you can see from the below screenshot from that game, the new one will be a tad prettier.
Nintendo said that gameplay will include new abilities for Samus and her famous suit, such as free aiming, a shooting method not possible on consoles with fewer controls than the 3DS.
It’s a sidescroller unlike the home console Metroid Prime series, but the 3DS can produce some stunning scenery, with gameplay previews showing deep colour palettes, smooth transitions and a great depth of field.
Nintendo has a brilliant track record of bringing new life to remakes. Even if you’ve played Metroid II: Return of Samus for hours, we have no doubt you’ll still want to get this.
Like most recent Nintendo games, Metroid: Samus Returns includes support for a few of the company's interactive Amiibo figures, which in this case will unlock exclusive content that you can't access any other way.
The game will release alongside two new Amiibo, one of Samus crouching and one of a Metroid enemy, but will also support the existing Samus and Zero Suit Samus figurines from the Smash Bros. series.
Each will unlock different content in the game. The new Samus figure will add an extra energy tank and some exclusive Metroid 2 art, while the new Metroid figure - which is squidgy (!) - will reveal the location of any nearby Metroid enemies on the map, and unlock a 'Fusion' difficulty mode after you complete the game, which lets you play with the suit from Metroid: Fusion.
The older Samus figure nets you an extra missile tank and exclusive concept art after you complete the game, while the Zero Suit Amiibo gives you another energy tank and the chance to listen to the game's soundtrack after you complete it.
