PowerRouge here with some madami news on the Sonic Franchise and Fandom with news of a new Sonic game to be announced mid-February!
The game's pamagat is yet to be released but I have news on gameplay! The game will start with Sonic being the only playable character, and as you progress through the TWENTY different stages (not including boss stages), you unlock madami playable characters, kinda like Sonic Adventure. (No new characters). Some characters will be able to complete certain levels easily while others will have trouble or can't complete it at all. For example: Sonic and Shadow can't climb walls so if you play as Tails or Knuckles, you can either fly or climb your way up.
The stages you play depend on how you reach the goal ring, however you still play the same final boss no matter which path you take. (Dont worry, it's not like Shadow the Hedgehog).
It will be released on all current gen consoles, including the Wii U and Nintendo 3DS. There are also rumours of it being one of the first games on the susunod Gen consoles, PlayStation 4 and Xbox 720, both to be released later this year.
When I find out the name of this mysterious new Sonic game, I'll rush and post it on here unbelievably quick! If anyone knows, write in the comments.

See ya
