Yeah, that's right, a remaster of Sonic Forces that fixes the story and gameplay along with including "Silver Forces" as another game.

Here's my boss ideas for Silver Forces:

1: Phantom Zavok

2: Phantom Chaos

3: Phantom Shadow

Final¹: Infinite & Phantom Metal Sonic

Final²: Metal Eternity (Infinite & P. Metal Sonic fused together)

(The bosses are NOT rehashes of base Forces' bosses, so don't worry!)

Within Silver's levels Infinite will appear and use (what's left of) the Phantom Ruby to change the stage into a twisted version of Crisis City.

I will share any more ideas I get, feel free to ask any questions about this lil' idea of mine.
