seems like a good price for a new release
Discovering an element known as Ragnium, Dr. Eggman starts 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.
Like the previous 3DS entry, Shattered Crystal, Sonic Boom: Fire & Ice is a side-scrolling platform game in which Sonic and his companions fight their way through various stages. In addition to Sonic, Tails, Knuckles and Sticks, Amy has been added as a playable character. Like the previous game, players can switch between characters at will in order to use their unique abilities such as Sonic's speed, Tails' flight, Knuckles' strength, Sticks' boomerang and Amy's hammer. A unique feature 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 2 at will. The game will also feature various special stages, bonus minigames, challenge rooms, and local 2-player modes.
