Our verdict on Hollow Knight Randomizer 4
Hollow Knight Randomizer 4 is an open-source mod for creating customized Hollow Knight playthroughs. It is aimed at players who want more control over item placement, progression, area access, and the amount of novelty or challenge in a run. The randomizer can include skills, charms, keys, maps, relics, grubs, geo, and boss rewards, while also supporting map-area, full-area, and room transition randomization. Its focus is narrow but deep: this is a tool for Hollow Knight runs rather than a general-purpose game randomizer.
Customization is the product’s defining strength. Documented logic rules govern item, location, transition, and state access, helping shape how randomized progression works. Settings cover skips, novelty, costs, start locations, start items, and progression depth. Users can save or load settings profiles and create shareable settings codes. Progressive item behavior, split movement and ability modes, and tracker, helper, and spoiler logs add further control and visibility during each playthrough. These options make it suitable for players who want to tune the structure of a run instead of accepting a fixed randomization format.
Hollow Knight Randomizer 4 is open-source and free, with no tiered product structure described. It requires Hollow Knight 1.5 or later together with several supporting mods and libraries, including integrations such as Benchwarp, QoL, MenuChanger, ItemChanger, RandomizerCore, and RandomizerCore.Json. Cooperative linked-game playthroughs are available through the separate HollowKnight.MultiWorld add-on. Choose it if detailed Hollow Knight randomization, logic control, and run tracking are priorities. Players seeking a standalone tool, a broader game catalog, or cooperative functionality in the base mod should look elsewhere.
