Sonic Forces

Sonic Forces (ソニックフォース Sonikku Fōsu?, lit. "Sonic Force") is an upcoming platform video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega. It is scheduled to be released on 7 November 2017 for PC, Nintendo Switch, PlayStation 4 and Xbox One. Sonic Forces follows Sonic the Hedgehog as he joins a resistance force against Dr. Eggman, who has taken over the world with the help of his army, henchmen and a mysterious new villain known as Infinite. The storyline of the game also ties into Sonic Mania.

The game will mark the return of the collaboration between both Classic Sonic and Modern Sonic, along with their associated gameplay styles, since the twentieth anniversary game Sonic Generations (although it is not a sequel to any previous games). In addition, Sonic Forces also introduces a third gameplay mode featuring the "Avatar", the player's own created character. The game serves, along with Sonic Mania, as a “continuation” of Sonic’s 25th anniversary.

Plot
Sonic Forces has the primary themes of "forces", "power", and "teamwork". This time around, the unthinkable has happened: Sonic the Hedgehog has failed and Dr. Eggman has won. While trying to stop Dr. Eggman's ambitions as usual, Sonic got caught by a mysterious enemy. Eggman subsequently defeated Sonic with the aid of a giant robot army and a new power he acquired from his new right-hand man: an enigmatic and powerful being known as Infinite. After that, Sonic disappears into thin air, with his friend Tails losing contact with him.

With Infinite's power and no Sonic to oppose him, Dr. Eggman manages to conquer 99% of the planet, resulting in his army controlling that much of the world. Amongst Eggman's evil group of henchmen are also the doctor's old allies: Shadow, Metal Sonic, Zavok, and Chaos. These enemies have managed to easily conquer the world on behalf of Eggman with the power provided to them, and are now ready to create more next-level panic and disorder. Meanwhile, Infinite has joined Eggman's side as the leader of his entire army. With Eggman out to crush the remaining opposition, multiple forces are now embroiled in conflict for the control of the planet.

Sonic’s disappearance was shocking news to everyone. Sonic’s friends, who managed to escape from Eggman’s invasion, decide to back by forming the “Resistance” army, with Knuckles the Echidna at the helm. As the Eggman Empire's armies lay waste to entire cities, Sonic returns and joins up with the Resistance. Classic Sonic, Sonic's counterpart from another dimension, appears soon after, having been brought to Sonic's dimension by the same power Eggman used to conquer the world. Also joining the Resistance is an active newcomer from a district of survivors that got attacked by Dr. Eggman’s army. This rookie has decided to fight to get the world back after meeting Sonic. Now, with the aid of his friends, the resistance rookie, and Classic Sonic, Sonic embarks on a mission to save the world and end the evil reign of the diabolical doctor and his forces. However, time grows short for Sonic, as the Resistance only has three days before Eggman unleashes a plan that will eradicate all his foes.
