What Hollow Knight MultiWorld is
Hollow Knight MultiWorld is a free, open-source set of add-ons for Hollow Knight Randomizer 4.0 that supports cooperative randomized play across linked game files. MultiWorld distributes items among players’ worlds, while the separate ItemSync add-on shares randomized pickups within a room. Players can use local randomizer mods, access their own settings, set nicknames that appear when their items are collected in other worlds, and coordinate with a room code. A random identifier allows multiple game sessions to run on one server. Players can save and reload, reconnect, and rejoin to recover MultiWorld data after a crash before their first save. Mods are available through Scarab, which installs dependencies automatically. The project documents a public server and local hosting with MultiWorldServer.exe; WAN hosting requires forwarding port 38281. The project lists Windows as its supported platform and uses the LGPL-2.1 license. Detailed spoiler logs containing information for all players are listed as a future feature.
