The Nintendo 2DS is a revision of the Nintendo 3DS, the second after the Nintendo 3DS XL. As its name suggests, the system lacks the ability to display 3D visuals, only projecting images in 2D. According to Nintendo of America President Reggie Fils-Aime, it is intended to appeal to younger consumers.  It was released in North America and Europe on October 12, 2013, for the price of $129.99 and £109.99, respectively, in black/red, black/blue, and white/red colors.  There are currently no plans to release it in Japan. 
The system cannot display Nintendo 3DS games in 3D.  However, it does contain dual cameras on its back, so augmented reality games can be played and 3D pictures taken -- however, the photos must be transferred to a 3DS or any other device that supports autostereoscopic 3D to actually be seen in full 3D. It features a "slate" design reminiscent of a tablet, ditching the clamshell design all Nintendo handhelds have yielded since the Nintendo DS. Due to this, the controls have been moved closer to the top screen, and the player must press a button to put the system into sleep mode. 
The system comes with a 4GB SD card, a stylus, and a charger. It only includes one speaker, which plays mono sound, but features full stereo via its headphone jack. The microphone has been moved to the lower left. The system features all of the wireless compatibilities of the regular 3DS, though WiFi must be turned off using controls in the software rather than with a physical switch. It also has StreetPass compatibility, but a switch must be toggled to enable it.
