Sonic the Hedgehog 2 (1992) was the game that introduced the Super Dash Attack. The ability, referred to as Spin Dash in later games, has become one of the most beloved features of the series and, indeed, one of the most prominent features of the speedrunning scene as a whole.
In this exhilarating movie, the authors speed their way through this classic's bonus stages to collect all 7 chaos emeralds, as well as the varied acts making good use of Spin Dashes to finish them in record time. The authors also control Tails — Sonic's two-tailed foxy buddy — to allow for even faster routes and making shorter work of bosses.
We have a run where Knuckles replaces the main characters and finishes the game in record time, and another run where he goes for the max rings challenge.
Every second link leads to a CamHack encode that keeps Sonic visible all the time.
