Sonic Forces

Sonic Forces (ソニックフォース Sonikku Fōsu?, lit. "Sonic Force") is a platform video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega. It was 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 to take back the planet after Dr. Eggman's Eggman Empire took over 99% of it with the help of Eggman's henchmen, the Phantom Ruby and a mysterious new villain known as Infinite. The storyline of the game also ties with Sonic Mania.

The game marks 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 custom-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 Sonic was absent, Dr. Eggman has managed to conquer 99% of the world with his army, thanks to a new power. Joining Eggman's group of evil henchmen in his agendas are Shadow, Metal Sonic, Zavok and Chaos who are ready to create more next-level panic and disorder. Also joining Eggman's side as the leader of the doctor's entire army is a mysterious and powerful new enemy known as Infinite. With Eggman out to crush any opposition, multiple forces are now embroiled in conflict for the control of the planet.

As the Eggman Empire's armies lay waste to entire cities, Sonic joins up with the “Resistance” members opposing Eggman. 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. Now, with the aid of his friends, a 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.

Gameplay
Sonic Forces includes three playable characters. Akin to Sonic Adventure 2, the story will be told from the perspective of each of these three characters as the player plays each one of them during the storyline, and when it all is put together it will tell the overarching story. The first two of these characters include Classic Sonic (Sonic's original design from the Sega Mega Drive Sonic games) and Modern Sonic (Sonic's revised form in Sonic Adventure and afterwards). Other main characters will make non-playable appearances in supporting roles, offering support and advice to Sonic via radio communication.
