Sonic the Hedgehog 4: Episode II

Sonic the Hedgehog 4: Episode II is a 2.5D platformer for next-gen consoles, and marks the second episode of Sonic the Hedgehog 4. It was announced saying it will have new zones and bosses and many other things we haven't seen before, plus it was said that thanks to the sales of the prior game, the game will likely have a bigger budget.

Story
A few months after the events of Episode I, Little Planet, where Sonic CD took place, approaches once more. Doctor Eggman, who was defeated in the previous installment, knew that was only the beginning of his big scheme that he had been planning in secrecy. Dr. Eggman planned the entire plan from the very beginning of Episode I.

Hearing that Little Planet has finally returned, Eggman eagerly hops back into action, the next phase of his scheme will begin to unfold. Elsewhere, Sonic's old robot rival Metal Sonic has survived his defeat back in CD, though was left on Little Planet when it disappeared before. Eggman finds the Metal hedgehog and has made him even more powerful than before, to make Sonic no match for him.

Meanwhile, Sonic has found out about the Doctor and Metal Sonic being back, so he recruits his buddy Tails to help him face this new threat and speed around the Little Planet once more and save it from destruction.

What was Dr. Eggman searching for in the Lost Labyrinth? What was Mad Gear built for? They were all a mere puzzle piece of a grandiose project schemed by Dr. Eggman. When Little Planet reappears, Dr. Eggman’s whole scheme will be revealed! Will Sonic and Tails stop Dr. Eggman and Metal Sonic's plan once and for all?

Description
Metal Sonic has returned to form a formidable alliance with Dr. Eggman. To face this new threat, Sonic will have to call upon an old friend to help him save the day. Joined by Tails, they utilize ingenious combination moves and race across four brand new Zones, in order to put an end to their evil plans. Play alone, or with a friend locally (and online), in an evolution of Sonic 2's collaborative gameplay! Unleash Sonic and Tails’ devastating joint attacks and combination moves to fight the united force of Metal Sonic and Dr. Eggman. Episode II features an all new game engine, bringing you updated physics and an original graphical style as you race through six unique Zones and a new Special Stage based on the one from Sonic 2.

Gameplay
Considerably changed from Episode I, Episode II will have a brand new physics and graphics engine, promising physics that are closer to how it was on the Mega Drive/Genesis. Ken Balough, brand manager of Sonic 4, said that fans gave bad reviews over the physics in Sonic the Hedgehog 4: Episode I as well as a brand new graphics engine, which is why it has been reworked.

Like Episode 1, the game is a 2.5D sidescrolling platformer, though it plays similar to Sonic the Hedgehog 2, with the addition of Tails. During regular gameplay, Tails follows Sonic around like he did in Sonic 2 and 3. A co-op mode has also been added, allowing one player to play as Sonic and the other as Tails. One of the game's most outstanding gimmicks is that Sonic and Tails can team up and do power combo moves allowing them to spin, fly, and swim. Homing Attack has also been added, just as it was in Episode I. Tails can also do the Homing Attack.

Trivia

 * This is the first game since Sonic & SEGA All-Stars Racing (or Sonic 06 in the mainstream games) to promote Tails as a playable character (not counting the digital re-release of Sonic the Hedgehog CD).
 * Also in creativity for promoting Tails, the art and styling for the game's beta box art represents Tails' two tails in place of the Number 2. This is also featured in the game's teaser trailer.
 * Also in the Teaser Trailer, Sonic and Tails performed a combined Spin Attack; which caused some fans to wonder if it in fact was a new move or not. With the recently released screenshots it is revealed that it is a move named Rolling Attack.
 * The color of Sandworm looks very similar to its iteration, Caterkiller.
 * This is the first Sonic game to promote Tails carrying Sonic underwater. The first to feature it was Sonic Advance 3 with Tails' mid air tag action.
 * This game celebrates the 20th anniversary of Sonic the Hedgehog 2. As well as the title card paying homage to said game (which is similar to Episode I which pays homage to Sonic 1), the Special stages are given a Sonic 2 style. This style of special stage was also previously used in Sonic 3D Blast, Sonic Pocket Adventure, Sonic Heroes, Sonic Rush, Sonic Colors (DS version) and Sonic Generations (3DS version).
 * One of the level screenshots strongly resembles the snowboarding segment from Sonic the Hedgehog 3 and Sonic Adventure, in Ice Cap Zone.
 * It appears that Metal Sonic has stolen the rocket Tails made, the one that is used to get to the Final Zone in Sonic 4 Episode I.
 * This game marks the return of Little Planet from Sonic CD.
 * The music in the 2nd trailer is a remix of the menu music from Sonic & SEGA All-Stars Racing. It's rumored that remix will be in the game.
 * Red Rings from Sonic Colors and Sonic Generations make a return, though what they'll unlock in the game has yet to be confirmed.
 * In the gameplay trailer the warning signs from Sonic Generations that mark bottomless pits are back and the image shows the Classic Era Sonic.
 * Super Sonic will be playable in ordinary boss fights, which is the first time since Sonic 3 & Knuckles to do so.
 * In Episode I people saw something on the right of the world map causing them to wonder if it was to Episode II. According to the world map of Episode II, it connects to Episode I.
 * Metal Sonic's artwork is extremely similar to his Sonic Generations artwork, except in his Modern design.
 * Ken Balough said that 2 Zones will come back from Classic Sonic games, one screenshot is probably one of the returning zones which looks like Oil Ocean.
 * In another interview with Ken Balough, a new trailer was shown on the interview revealing a new zone for the game which can possibly be Oil Ocean. The trailer also revealed that, for owners who purchased Episode I and the upcoming Episode II, they will get a free additional episode on the same device for free. The additional episode is called Sonic the Hedgehog 4: Episode Metal. A game that allows you to play as Metal Sonic. In this extra episode, it features stages from Episode I along with four exclusive zones for Metal Sonic.
