Sonic the Hedgehog 2

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, Aglar & Zurggriff speed their way through this classic's 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.

This is an improvement of 00:12.90 seconds over the predecessor movie.

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.

We also have movies in Sonic the Hedgehog, Sonic the Hedgehog CD and Sonic 3 & Knuckles.

Every second link leads to a CamHack encode that keeps Sonic visible all the time.

This is an official version of Sonic the Hedgehog 2 with Sonic & Knuckles locked on it. Here, the title character is replaced by his rival, Knuckles, who has his signature abilities of climbing and gliding carried over to this version. Other than that, the levels are unchanged. If you haven't seen Sonic the Hedgehog 2 completed before, you may wish to do so before seeing what a character with spiked knuckles and gliding can accomplish.

Takz15x and ShiningProdigy9000 save a little over 52 seconds over the previous run thanks to a couple of new tricks and strategies.

For more Knuckles in Sonic 2, we have a run of him just beating the game as fast as possible without having to collect the Chaos Emeralds and a run where he collects nearly every ring in the game. We also have a 100% run with Sonic and Tails instead.

There are also alternate CamHack encodes that attempts to keep Knuckles visible on the screen as much as possible and over any sprite layers.

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 and tails to finish them in record time. They also manage to save 15.6 seconds over the previous run thanks to new routes and strategies. For more details on that, you can read their notes here.

This game is what you get if you take Sonic the Hedgehog 2 and lock it onto Sonic & Knuckles. As the name suggests, what you get is simply Sonic the Hedgehog 2 with Knuckles the Echidna as the playable character. The levels remain mostly unchanged, save for the addition of a few monitors that can only be reached as Knuckles, whose abilities from Sonic and Knuckles (gliding, climbing walls, and jumping a little lower than Sonic) remain intact.

In this run, you'll see the zones of Sonic the Hedgehog 2 (colloquially referred to as West Side Island in the Japanese manual) like you've never seen them before, as Knuckles uses every trick in the book to collect over five thousand rings, with only 11 throughout the game eluding his grasp. (For the time being, anyway...)

We also have runs with Sonic and Tails and Knuckles in this game.
