The sleek console resembles a normal DS but boasts a hoard of new upgrades, including better graphics, a widescreen upper display, in-built motion sensors and a Slide Pad for precise analogue control.
However, the headline feature is its 3D visuals, which allow players to experience three-dimensional images without the need for special glasses.
It will include a slider to adjust the level of the 3D effect and will be able to play back 3D Hollywood films such as How to Train Your Dragon, while the in-built cameras will even let users snap three-dimensional photos.
Nintendo video game designer Shigeru Miyamoto said: "The additional dimension of depth in 3D makes it easier for players to judge distances while giving developers a new tool to create games and experiences that play with both height and depth."
The 3DS' impressive range of features will no doubt help to convince gamers that it is a worthy successor to the DS, which earlier this year became the best-selling console ever launched in the UK.
