This time around it focuses on the special and bonus stages, which include the brand-new Sonic CD inspired 3D sequences and the return of Sonic 3's Blue Sphere. In Special Stages, meanwhile, you'll chase down UFOs to unlock a Chaos Emerald, while collecting blue spheres gives you a speed boost. Touching any red sphere ends the stage. Collect all blue spheres and all rings, and you'll achieve a ideal score and a Gold Medallion.
Lastly, Sega introduced a time attack mode that supports all three characters in the game - Sonic, Tails and Knuckles. This pixel-perfect homage to the Genesis/Mega Drive games that made Sonic a star is the flawless blend of retro and reinvention, capturing the precise, borderline magical, feel of the running and jumping from the original games while weaving in all kinds of ingenious new stage mechanics and level design. If you hit a flawless score, you will receive Gold Medallions.
Long story short, the Bonus Stages suffer from the worst flaws of many platformer's bonus bits: instead of testing your mastery over the core game mechanics, they saddle you with an unfamiliar, uncomfortable control scheme in the name of gimmicky presentation.
The second feature is the special stages. The stage has yellow balls that make Sonic jump and white balls that the hedgehog bounces off of.
You access Special Stages by seeking out giant polygonal rings hidden within each level.
Unfortunately, Sega left that as a mystery, but the stage adds to the retro feel of "Sonic Mania". The special stage puts Sonic in something similar to an infinite runner. We also get a brief look at the time trial mode.
Sonic Mania will be available August 15, 2017 on the PS4, Nintendo Switch, Xbox One, and PC. Prove you're the best of the best in Time Attack, which lets players compete for fastest speed in the world by recording their time in the game's online leaderboard.
