The Happy Couple achievement in Hollow Knight normally takes a bit over an hour to complete. But what if two players did it collaboratively, sharing their progress? And what if those two two players were both TAS? In this tool-assisted speedrun, our knights Alice and Bob work together to unite Sheo and the Nailsmith as quickly as possible. Much thanks to everyone who helped make this video possible, including the many folks on the HK TAS Discord and, specifically: @mathulu for the starting point of the route and for the itemless blue lake setup, as well as hosting the reveal stream @quacksilver3393 for providing the teaser audio at the end for the alternate ending @dragon_nyx for the wonderful title art Technical notes: This video was created by using libTAS to provide deterministic playback, with custom scripting to synchronize progression between the two separate TASes. To improve viewing, the knight was given lantern from the start, with the 'dark rooms' then altered in post-production to clarify that they're intended to be dark; this has no gameplay effect, as the TAS doesn't do any hazard respawning in the dark rooms. Once both TASes were complete, going back and forth to keep them in sync, the two videos were encoded and then edited together to produce the final product.
