Lifeblood Icon Lifeblood is an update to Hollow Knight which was officially released on the 20 April, 2018, after a period in public beta. As it was not one of the three originally planned DLC updates, it did not release with a teaser. The update focused mainly on enhancing technical aspects of the game, bringing upgrades and optimizations of various kinds. However in later trailers and references, it is noted to be a content pack.
