When you boot up Sonic Legacy, it first appears as a mod called RodentRap, your average Sonic mod that looks like it would've been made in the more early days of FNF. At first when you play 2Torial and Free-4-Me, everything seems fine and safe for the player. Until however, Sonic asks you one question, "Do you want to play with me?" After this, X reveals himself and the mods true nature, as like a rodent, you're caught in his trap. Now, you, the player, have to rap battle your way out of his game before it's too late. "Let's see long you can last."
