The game was intended to have a darker tone compared to previous entries in the franchise, and the character creation system was inspired by Sonic fan art the developers had come across over the years. The game's title was chosen to signify its themes of power, teamwork, and armies. It features three gameplay modes: 'Classic', side-scrolling gameplay similar to the original Sega Genesis Sonic games 'Modern', 3D gameplay similar to Sonic Unleashed (2008) and Sonic Colors (2010) and a mode featuring the 'Avatar', the player's custom character.ĭevelopment of Sonic Forces began after the release of Sonic Lost World in 2013. Together they must stop Doctor Eggman, who has conquered most of the world alongside Infinite, a new enemy, who wields the power of the Phantom Ruby, and is able to create limitless numbers of illusionary clones of past villains. Sonic the Hedgehog joins a resistance force alongside Classic Sonic, his past self, and the Rookie, a survivor of Eggman's attacks. It was produced in commemoration of the 25th anniversary of the Sonic the Hedgehog franchise. Sonic Forces is a platform game developed by Sonic Team and published by Sega.
