To kick start Sonic’s 20th anniversary, Sega have released a trailer for a new Sonic game. Sonic the hedgehog 4 Episode 2 should be released this year, the sequel to Sonic 4 Episode 1 which was released in October last year. However this trailer doesn’t look like Episode 2 of Sonic 4 but, rather a new game entirely. Speculation is that the game may see retro sonic go head to head with next gen sonic, or both of them working together. What are your thoughts? Check out the trailer below.
