A growing video collection of miscellaneous strategies taken by different runners on different parts of Sonic 3 & Knuckles that aims to serve as a complement to the existing level tutorials. Includes both clips showcasing strats designed to make the speedrun easier (e.g. slower but more consistent methods) and more consistent (e.g. softlock avoidance methods), as well as recent developments that can be used to further accelerate top-tier attempts.

As of today, any new submissions of S3K from the Steam version will no longer be allowed. This is due to a couple of factors but mostly being inhibited availability as SEGA delisted it when releasing Origins. Any existing runs will remain unaffected.
