Hollow Knight MultiWorld vs Hollow Knight Randomizer 4

Hollow Knight MultiWorld is a free, open-source set of add-ons for Hollow Knight Randomizer 4.0. MultiWorld distributes randomized items across linked game files for cooperative play, while the separate ItemSync add-on shares randomized pickups among players in a room. Players can use local randomizer mods, keep their own randomizer settings, choose nicknames shown when their items are collected elsewhere, and coordinate through a room code. The server assigns a random identifier to each randomization, allowing multiple sessions to run at once. Players can save, reload, reconnect, and rejoin to recover MultiWorld data after a crash before their first save. Mods are available through Scarab, which installs dependencies. Documentation lists a public server and explains local hosting with MultiWorldServer.exe; WAN access requires forwarding port 38281. The project supports Windows, offers advanced customization, seed sharing, and multiworld support, and is licensed under LGPL-2.1. Detailed spoiler logs are planned.

Hollow Knight Randomizer 4 is a free Windows mod that changes item placements and transitions for Hollow Knight patch 1.5 and later. Item pools can include skills, charms, keys, shards, relics, maps, grubs, and boss essence. Transition settings range from no randomization to Map Area Randomizer, Full Area Randomizer, and Room Randomizer. Additional options include Randomize Swim, Randomize Nail, Split Claw, Split Cloak, and Split Superdash. Players can save and load settings profiles, and generate shareable codes for base randomizer settings; codes correspond to a specific mod version. RandoSettingsManager can synchronize randomizer settings and most connection mod settings, with an internet connection required for its codes. The mod writes tracker, helper, and spoiler logs to the Randomizer 4 folder in the save directory. It requires Hollow Knight Modding API for patch 1.5 or later, MenuChanger, ItemChanger, RandomizerCore, and RandomizerCore.Json. It does not support Hollow Knight patches 1.4.3.2 or earlier. Benchwarp and QoL are strongly recommended and may be necessary for some logic or modes. The repository identifies the license as LGPL-2.1.
