Sonic Boom: Fire & Ice is an action-adventure platform game developed by Sanzaru Games and published by Sega for the Nintendo 3DS.

It is the third video game based on the Sonic Boom TV series and the sequel to Sonic Boom: Shattered Crystal. It will be released exclusively on the Nintendo 3DS. 

Sonic Boom: Fire and Ice is a side-scrolling platform game, with focus on speed and optional exploration, where the player has to get through various levels with Team Sonic. For this game, the characters’ movesets have been revamped from Sonic Boom: Shattered Crystal, retaining the same moves from before and are given new surprises as well.

Like in the previous game, the player can instantly switch between the characters during gameplay using the touchpad. Each character has their own unique abilities such as: Sonic’s mid-air dash, Tails’ flight, Knuckles’ burrowing, Sticks’ boomerang, and Amy’s hammer for progressing with the levels. The characters also have a number of common skills such as the Homing Attack to home in on enemies, and an Enerbeam for traversing certain areas. Like in the previous game, this one also contains a variety of collectibles.

A unique gimmick in this game is the addition of fire and ice elements, which apply both to the level environments and character abilities. For example, Sonic can infuse himself with fire to break ice blocks or surround himself with ice in order to freeze water, alternating between the two at will.

The game will also feature various special stages, bonus minigames, challenge room, and local two-player modes.
