Sonic Forces is a 3D platformer where you run through levels as three different characters. Modern Sonic handles speed sections in 3D, Classic Sonic tackles 2D sidescrolling stages, and you create a custom character who uses gadgets like grappling hooks and flamethrowers. Dr. Eggman's conquered the world with help from a new villain called Infinite, and you're part of a resistance trying to take it back. Levels mix automated dash sequences with platforming across crumbling cities and industrial zones. The custom character system lets you pick species and equipment loadouts that change how you approach obstacles. Each playstyle feels distinct—Modern Sonic's about maintaining momentum through scripted setpieces, Classic Sonic requires tighter jumping, and your Avatar blends both with tool-based shortcuts. It's structured around replaying stages for better times and collectibles.
