The Game Was Released On Wii U In Hedgehog/Groundhog Day, 2012.
Modes Of Play
The Main Mode Of Gameplay. You Can Play As Either Sonic, Tails, Sonic & Tails, Or Knuckles.
A Complete Remake Of The Level Layouts, Making The Game More Speed-Oriented. Also, Sonic Can Perform A "Speed Burst", Akin To That Of Sonic Rush. Each Level Has The Objective of breaking a set Record. Once You Do, You Get A Chaos Emerald.
Exclusive To Knuckles. The Level Layouts are more exploration-oriented, And There Are No Special Stages. Instead, The Emeralds Are Spread Throughout The Level, Just Like The 8-Bit Sonic Games. Knuckles Mode Is Unique In That It Includes Levels Scrapped In The Original, Like Wood Zone.
This Mode Is Available By Pre-ordering the Game. A "Hard Mode" Of Sorts, Metal Sonic Can Hover And Fly Indefinitely, Making this an improved form of Tails' Gameplay. All Enemies Are Harder To Defeat, And Metal Sonic Has NO Super Form! The Eggmobile Bosses Are Usually Controlled By Egg Robo, But The Final Boss Is Always Sonic. For Players who Haven't Pre-ordered, This Mode Is Still Available As DLC.
Online Multiplayer Mode
You Can Access This Mode Online. It Is An Emerald Hunt Of Sorts, Where The Seven Emeralds Are Spread Throughout The Level. You Can't Carry More Than One Emerald, Having To Place It At The Emerald Pod In The Middle Of The Level. All Players Start at the middle of the level, And Each One Of Them Can Play As Sonic, Tails Or Knuckles.
SonicSonic Claims To Be The "Fastest Thing Alive". He Is An Anthropormorphic Animal In A Small Planet Named Earth (Often Times Erroneously Called Mobius), And Due To A Mutation, His Spikes Are Blue. Sonic's Parents Are Unknown, But Sonic States That He Left His House After Eggman's First Defeat.
Sonic's Nemesis Has Always Been A Man Named "Eggman", Or Dr. Robotnik For Others, Who Tried Using Animals As "Organic Batteries" To Power His Robots. After His First Defeat, Eggman Focuses His Efforts Fully Into Erasing Sonic From Existence, Even Creating Robots Based On Him. Of These, Metal Sonic Has Had Most Success.
Other Times, Sonic Has Battled In Other Universes, In The Future, Even In Other Planets, Sometimes Battling Eggman, Sometimes Not.
Metal SonicMetal Sonic Is The Second Robot In The Metal Series, After Silver Sonic (Or Mecha Sonic, As Nicknamed By Tails). He Was Used In A Plot By Eggman To Capture Gems Known As "Time Stones" Residing In Little Planet. Afterwards, Metal Sonic Captured Amy Rose, Intending to use her to lure sonic to his location. Unfortunately, Metal Was Defeated By Sonic.
One Year Later, Metal Was Awakened By Eggman On Mad Gear Zone, Then Leaving To Find Sonic During The Events Of Sonic 4. Ultimately, Metal Sonic Was Defeated, Leading Him To Be Repaired During Sonic Adventure. In His Other Appearances, He Has Been Defeated Time And Again By His Organic Counterpart, Leading to him Becoming Extremely Hateful Of Sonic.
He Once Rebelled against Eggman, But Is Now Fully Loyal Again.

He Was Constantly Bullied By Other Orphans, And Spend Most Of His Time Reading And Building Things. One Of These Was The Tornado. One Day, Tails Was Being Bullied By Two Teenagers When Sonic Arrived And Saved Him. To This Day, He Keeps Following Sonic Around.

To Do So, He At First Used Organic Batteries For His Robots, Though Lately He Prefers Using A Mass-produced Fusion Reactor, Which He Also Sells To Fund His World Domination Attempts. At First He Used Varied Models Of Robots On His Takeover Of South Island. When His Robots Discovered Gemstones Called "Chaos Emeralds", Whose Powers Are Unlimited, Eggman Was Keen On Taking Them. Using His "Chaos Energy Detector", Eggman Found Six Emeralds, While The Last One Was A Keepsake Of Sonic The Hedgehog's. Eggman Tried Forcing Him To Hand It Over, But Sonic Quickly Ran Away.
