The new Sonic Origins offers players the chance to play classic titles while introducing new gameplay modes, like Mirror Mode.
Sonic Origins is a celebration of Sonic's birthday, bringing four classic Sega Genesis titles to modern consoles: Sonic the Hedgehog 1, Sonic 2, Sonic 3 & Knuckles, and Sonic CD.
This follows a recent trend of bringing back retro-styled games, like TMNT: Shredder's Revenge. The titles are remastered for modern consoles, although players have the option of playing them in the original 4:3 aspect ratio, called Classic Mode.
In addition to Classic Mode, Sega has remastered all four games for widescreen play in Anniversary Mode. This isn't the only new game mode; players can also unlock Mirror Mode.Read more on screenrant.com
