Sonic Forces

Sonic Forces (ソニックフォース, Sonikku Fōsu) is a 3D/2D platformer video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega. It was released in November 2017 for Microsoft Windows, 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 99.9% 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 into 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 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.
