- Tagline

Sonic Boom: Fire & Ice is an upcoming 2D side-scrolling action-adventure platform game, developed by Sanzaru Games and published by Sega. It is the third video game based on the Sonic Boom, following Sonic Boom: Rise of Lyric and Sonic Boom: Shattered Crystal. It will be released exclusively on the Nintendo 3DSfor the holidays in 2015.

Plot
When discovering a new element called Ragnium, which proves to be a powerful fuel when melted down and combusted, Dr. Eggman makes it a part of his latest scheme to humiliate Sonic by making his henchmen robots faster than the blue hedgehog. As Eggman works to obtain the Ragium, he pollutes the environment.

The main story follows one of Eggman's henchmen called Defect, who was designed to find Ragnium and mine it by using his eco magnets to raise it out of the ground. However, Defect malfunctions as soon as Eggman turns him on. Instead, Defect can magnetize everything other than Ragnium, so he begins to use his powers to build himself up so he can beat Sonic. To prove Eggman wrong and restore the environment, Team Sonic set out to defeat the rival racer robots, who have taken residence on seven different islands.

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 exclusive to each of the four characters are shown below:
 * Being able to use Sprint to traverse the stage faster.
 * 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.
 * Can coat themselves in an aura of Fire to break ice, and coat themselves in an aura of Ice to freeze water.
 * 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.
 * Amy Rose: Can use her hammer to peg in certain items and can triple 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 has a blaster that can bounce off mirrors, and is the only one who can activate the Sea Fox submarine by pressing X near certain monitors.
 * 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.
 * 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.
