Sonic Boom: Fire & Ice is a 2D side-scrolling action/adventure game, produced and developed by Sanzaru Games, and will be released exclusively on the Nintendo 3DS and Nintendo eShop. The game plays as the sequel to Sonic Boom: Shattered Crystal. 

Playable characters
The game contains five playable characters: Sonic, Tails, Knuckles, Sticks, and newcomer to the 3DS version, Amy Rose, who can be switched to at anytime via the touch screen of the 3DS (provided that they are unlocked). All four of the playable characters have access to the same moveset, though each one has their own special abilities. The abilities that everyone can perform are as follows: The abilities exclusive to each of the four characters are shown below:
 * Being able to Sprint to traverse the stage faster and in crease jump distances.
 * Jumping/performing a double-jump.
 * Performing a downward stomp.
 * Using the Homing Attack.
 * Making use of the Enerbeam to remove enemy shields and swing from floating mechanisms that are scattered throughout the levels in order to reach new areas.
 * Sonic the Hedgehog: Can perform a mid-air dash in four different directions, allowing him to break through special blue blocks and kill enemies in one hit like Knuckles. He is the only character who can perform the Spin-Dash, and is the fastest of the four with the highest jump to boot.
 * Sticks the Badger: Can throw boomerangs that do the same amount of damage as a Homing Attack. By tapping the X button, she can toss a short-range boomerang in any of the four main directions, but by holding the button, she can throw one that can be controlled mid-flight for a short while. Both of these methods can be used to both hit faraway switches, grab items, and to attack enemies.
 * Knuckles the Echidna: Can dig underground in certain spots for a limited time, and can perform a punch move in four different directions to take out enemies. By making use of these punches, Knuckles can one-hit-kill enemies that normally require more than one hit to defeat. He is the slowest of the group and has the weakest jump.
 * Miles "Tails" Prower: Can use his twin-tails to glide across wide gaps, but unlike his counterpart from the mainstream games, he needs wind in order to gain altitude, and as a result cannot actually fly. By riding air-currents though, he can reach high-up areas. He can also throw bombs that home in on and stick to enemies damaging theme with the strength of a Homing Attack after a timer goes off, and is the only one who can activate the Sea Fox submarine by pressing X near certain monitors.
 * Amy Rose: Can use her hammer to peg in certain items and can triple jump.
