Sonic and Shadow

Sonic and Shadow (A.K.A Sonic + Shadow Super Duo, Sonic VS. Selkadoom, and Sonic Adventure: Selkadoom in other Countries) is a 3D Platfomer Game and a Spin-off to the Sonic Adventure Series. It Folllows Two Rivals: Sonic and Shadow In a Battle Against a New Evil Creation: Selkadoom The Hedgehog and his Mission to Destroy Sonic and Shadow and become the one and true Ultimate Life-Form. The Game being a Spin-off to the Adventure Series, plays nearly exactly the same way, acting like the Fan-wanted Sonic Adventure 3. The Game has 4 Game-plays, 2 Stories, and a Final Boss Battle.

Gameplays:

Sonic: Plays as a Replica to Sonic Adventure 2. Not much changes.

Shadow: Plays Identical to Shadow the Hedgehog, but smoother, fewer guns, and more Identical to Sonic Games. (Shadow can only use Guns on Bikes, as a Stage Event)

Rivals (Sonic and Shadow Together) Plays like Sonic Heroes, but as a Pair instead of a Trio. Shadow and Sonic can do Team Attacks like Rival Spin Dash and Biker Duel Dash.

Selkadoom: Completely Original. It Features Mini-Stage Quests and Objectives. It is more bent on Destruction and Combat than the other 3 Gameplays.

Final Boss: Fly around as Hyper Sonic or Hyper Shadow. Remixed Versions of Respective Character Plays.

Stories:

Doomsday: First Story, Sonic and Shadow's Story.

Pastday: Second Story, Selkadoom's Story.

Final Boss Battle: Last Story, Hyper Sonic and Hyper Shadow's Story.

The Game is Story-Based, making Players switch between Sonic > Shadow > Selkadoom without will for the sake of the story. Each character has a Super Form which can be attained by exploring each Level carefully and getting through the Special Stage to get the Chaos Emeralds. Special Stages are easy, all you have to do is complete easy Mini-Games from the Adventure Series, like Find the Broken Rings or Escape Metal Sonic. These Stages are also not Real, but Selkadoom's Illusions. Super Transformations are completely optional and unimportant, as the Main Transformation of the Game is the Hyper Transformation, which is attained in the Final Boss Battle when Sonic and Shadow directly take some of the Master Emerald's Power. Super Transformations all used if you have all Seven Chaos Emeralds, have 50 Rings, and jump in the Air then use the Action Button. It makes Invincible for a Temporary amount of Time.
