Sonic Generations (PC): All Rooftop Run Modern Challenge Acts (S-Ranks)

With Sonic Forces coming out real soon, I've decided to hop back on Sonic Generations and make videos for it leading up to the game's release. I will be making S-Rank videos for all of the challenge acts in each zone for each character in Sonic Generations, starting with Classic Sonic in Green Hill and ending with Modern Sonic in Planet Wisp. Enjoy! ^_^ Twitch:   / darkspinessonic   Twitter:   / darkspinessonic
