Hollow Knight MultiWorld review
A focused Windows add-on for cooperative Hollow Knight randomizer sessions.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Hollow Knight MultiWorld is an open-source add-on for Hollow Knight Randomizer 4, designed for cooperative multiworld play. It links multiple game files and distributes item placements between them, so players collect items intended for other participants. The project suits groups that want shared progression rather than separate randomizer runs, with per-player settings, visible nicknames, and concurrent multiplayer sessions.
Its standout feature is linked progression across game worlds. When one player finds an item belonging to another participant, the item is delivered to the corresponding game, making cooperation central to the playthrough. Room codes help coordinate sessions, while reconnectable play, reloadable saves, and rejoin support after a crash address common interruptions. Players can use a public server or run the dedicated server themselves, giving technically comfortable groups more control over how sessions are hosted.
The main trade-off is focus. Hollow Knight MultiWorld is built around a specific game and randomizer ecosystem, and its published platform support is Windows. It also does not have verified logic randomization, so players seeking confirmed progression logic should consider an alternative. Choose this project for linked cooperative Hollow Knight sessions where recovery features, room coordination, and self-hosting matter. Choose another tool if you need broader platform coverage or a randomizer with verified logic.
