Silver Generations. Continuing the precedent established by Shadow Generations (Sonic Generations has nine zones and Shadow Generations has six), it has three zones: some random one from Sonic 2006 that isn't Crisis City or Kingdom Valley, Luminous Forest from Sonic Forces because that's where Silver has a scuffle with Infinite, and one entirely new level which is later reused in the next game where Silver has a major appearance. Because Silver is from the future, and so one of his levels is from a game that hasn't come out yet, you see.
