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.
Discovering an element known as Ragnium, Doctor Eggman begins harnessing it for himself, using it to create robots that can allegedly outrun Sonic and his friends while also damaging the environment in the process. Meanwhile, D-Fekt, a rejected robot Eggman created to search for Ragnium, starts using his magnetic powers to try to become more powerful. Sonic and his friends attempt to stop Eggman and D-Fekt and restore balance to the environment.
