Sonic Boom: Fire & Ice (known in Japan as Sonic Toon: Fire & Ice) is a 2.5D side-scrolling platformer developed by Sanzaru and published by Sega for the Nintendo 3DS on September 27, 2016.
It is the sequel to Sonic Boom: Shattered Crystal and the fourth game in the Sonic Boom series (based on the French-American CGI-animated television series of the same name, itself a spin-off of the Sonic the Hedgehog game series).
This game follows Sonic the Hedgehog and his five companions (Tails, Knuckles, Amy, and Sticks) as they work together to foil the plans of Dr. Eggman (who have begun mining a newly-discovered element known as Ragnium) and Eggman mining robot D-Fekt (who uses his malfunctioning magnetic powers to become more powerful).
Like Shattered Crystal, players can switch between each of the five heroes, each with their own special abilities. New to the game is the ability to manipulate fire and ice elements for the heroes' advantage.
