Sonic Lost World

Sonic Lost World (ソニックロストワールド) is an upcoming video game and the next main installment in Sonic the Hedgehog series. The game is being released exclusively for the Wii U and Nintendo 3DS, and both versions are slated for a Fall 2013 release. The game is currently under development by Sonic Team for Wii U and Dimps for Nintendo 3DS, and is to be published by Sega.

Story
Sonic is chasing after his longtime foe, Eggman. He encounters a mysterious floating island known as “Lost Hex,” where he'll run across the Deadly Six and learns that Eggman used them to harness their power until they rebel against the Doctor himself and threaten to destroy the planet. Sonic and Eggman are forced to work together in order to save the planet and put an end to their misdeeds. .

Gameplay
The player controls Sonic the Hedgehog in an action platformer. The setting of the gameplay takes place on spherical worlds that shift in perspective, allowing for both 2D and 3D gameplay. Similar to past instalments in the series, the player has to reach to the end, where the single capsule, which contains animal friends that are ready to be released from the capsule. After pressing the large button on the top of capsule, the player has completed that act in the zone.

The boost-integrated gameplay from previous 3D titles has been eschewed in favor of a new control style. On the Wii U version, using the D-pad will move Sonic at a moderate pace, whilst holding down the right trigger button will engage his running speed. Pressing both triggers allows Sonic to perform Spin Dash. The game introduces also the "parkour" system, which is allowing Sonic to maneuver across obstacles and climb walls. The Homing Attack can be chained in quick succession. The game will also feature returning and new Color Powers, gained from Wisps, a returning element from Sonic Colors, with different Wisps exclusive to both versions of the game.

The 3DS version of the game will also contain fully 3D gameplay similar to the Wii U version, unlike the handheld versions of Sonic Colors and Sonic Generations. The 3DS version will not, however, will not be a port, but rather, a separate game with different level design, similar to the handheld versions of Sonic Colors and Sonic Generations, and use slightly different controls due to the 3DS's button layout, compared to the Wii U controller. It will also offer four player local and online multiplayer modes, and connectivity with the Wii U version of the game.

According to the IGN Walkthrough on June 7, 2013, Sonic Lost World will contain numerous references to many of the past Sonic games, such as the Super Peel Out animation when Sonic gains a certain amount of speed, and the Red Star Rings from Sonic Colors and Sonic Generations, which can collect as unlocking collectible content. While capsules, that release Animal friends, do appear in not only the end of each stage, there are smaller capsules throughout the zones themselves.

Development
Originally, Sega registered the trademark and the web address of the game's website on May 16, 2013. The game was first announced at a presentation of Nintendo Direct on May 17, 2013. According to Nintendo's Satoru Iwata, it is announced that Nintendo itself has entered into a worldwide partnership with Sega regarding the Sonic the Hedgehog franchise.

The first teaser image was revealed during the Nintendo Direct, showing Sonic and Tails flying with Tornado to the new main setting of the game, later being revealed and named as Lost Hex. A week later, Sega uploaded another teaser picture to the Facebook account, which showed silhouettes of mysterious new characters. On May 28, 2013, the debut trailer came out, released by IGN instead of SEGA revealing the mysterious enemy group called as Deadly Six and showing the first gameplay clips. The next day, story details, new gameplay mechanics and collectible contents was revealed.

On June 7th, 2013, Richard George on IGN showed a walkthrough tutorial of Windy Hill and Desert Ruins with Aaron Webber. More information is to be revealed by the game's development team in an upcoming event celebrating Sonic's 22nd anniversary, which is held at Tokyo Joypolis.

Trivia

 * Sonic's original Tornado is seen in the concept artwork but is slightly altered from the last version seen in Sonic the Hedgehog 4: Episode II.
 * This game shares its name with an action stage from Sonic Adventure.
 * The music used in the debut trailer is a instrumental version of "Cinema" by Benny Benassi.
 * The music also seems to resemble the chord structure of the Rooftop Run theme.
 * The Super Peel Out makes a return in the game as Sonic's standard running animation, which was last seen in Super Smash Bros Brawl.
 * The game shares some similarities to Sonic X-treme, a cancelled game for the Sega Saturn. Both games have a story where six creatures get out of Eggman's grasp (which was one of several stories for the latter), both have  a first stage inspired by Green Hill Zone (the former Windy Hill and the latter Jade Gully Zone), both have freely floating level structures and both have gravity playing as key role. It also shares some similarites to Super Mario Galaxy, another game that has freely floating, circular level structures and has gravity playing a key role.
 * The Badniks in Lost World bear cartoonish designs rather than their more menacing designs used in recent games like Sonic Colors and Sonic Generations.
 * This is the second main series Sonic game to feature a double jump after Sonic Colors. The handheld version will also be the 2nd game in the handheld series, the first being Sonic Blast.
 * The Invincibility's and Speed Shoes' theme is an instrumental version of Sonic Heroes.
 * Large floating cannons in this game are similar to ones from Oil Ocean Zone in Sonic the Hedgehog 2.
