Sonic Boom: Shattered Crystal

Sonic Boom: Shattered Crystal is a 2014 platform game developed by Sanzaru Games and published by Sega for the Nintendo 3DS. Along with its Wii U sibling Sonic Boom: Rise of Lyric, Shattered Crystal is a spin-off of Sega's Sonic the Hedgehog franchise and is a part of the Sonic Boom sub-franchise, which also consists of an animated television series, whose games serve as its prequels. The two games together formed the third and final part in Sega's exclusivity agreement with Nintendo, following Sonic Lost World and Mario & Sonic at the Sochi 2014 Olympic Winter Games in 2013.
