High on Knife is a 2023 shooter-adventure expansion developed by Squanch Games, available on Xbox One, Xbox Series X|S, PlayStation 4, PlayStation 5, and PC. Set two years after the conclusion of the original High on Life, the add-on centers on the player's talking arsenal — specifically Knifey, who receives a mysterious package from home. This delivery sets off a new adventure involving the player and their sentient weapons. The expansion maintains the irreverent tone and talking-weapon combat mechanics established in the base game, extending the narrative into fresh territory prompted by Knifey's personal backstory. As a follow-up chapter rather than a standalone title, it builds directly on the world and characters players encountered in the original, offering a self-contained story arc rooted in one weapon companion's unexpected connection to their origins.
