Sonic Boom: Fire & Ice is an action-adventure platform game developed by Sanzaru Games and published by Sega for the Nintendo 3DS. It is part of the Sonic Boom spin-off franchise of the Sonic the Hedgehog series, along with the games Rise of Lyric and Shattered Crystal and a television series. Originally planned for a release in late 2015, Fire & Ice was released in North America and Europe in September 2016, and in Australia the following month. While the game received mixed reviews, it was seen as an improvement over Rise of Lyric and Shattered Crystal.
