Sonic Boom: Fire & Ice
Dr. Eggman has discovered the supercharged element ragnium on the mythical Island of Ragna Rock. He mines it as a fuel source, piping off the messy by-products of the operation to adjacent islands, creating fire and ice gameplay. Using this fuel to power his ultra-fast bot racers is his latest plan to discredit his eternal rival Sonic, but backed by ragnium, fire and ice, a robot army, and D-Fekt, an unflinchingly powerful henchman, this time Dr. Egg man just may succeed. Sonic and friends must reclaim each island by destroying enemies, vanquishing the Island Defender, winning rival races, and reversing the flow of the elemental tubes. It all culminates with an epic battle on the Island of Ragna Rock where Sonic may just have to save Dr. Egg man from his own creation.
