About this mod Author’s original text

Fusion Syringe — experimental

PCVR MelonLoader add-on for the ordinary syringe in Bugrax.BLSyringe. This is an independent add-on, not the original syringe pack.

Build verified only. Two-player in-game testing has not been performed.

Required content

Install Syringes (Patch 6) separately. Its assets are not included or automatically installed by this package. Keep Fusion and BoneLib installed, with a working MelonLoader setup. Standalone Quest is not tested.

Usage

Open BoneMenu > Fusion Syringe. Spawn the ordinary syringe, displayed as Syringe (Fusion) when the add-on finds its crate.

  • DLL у игроков (default): the recipient needs this DLL. Sends a targeted 20-second knockout with ragdoll and movement suppression. The sender need not be host. Lobby rules are not changed.
  • Без DLL у остальных [Хост]: select while hosting an active Fusion lobby. Other players need Fusion but not this DLL. A detected stab sends native Fusion damage; the recipient's normal Fusion knockout handler is expected to apply the effect.

The current trigger is a detected stab, not Y/B. This does not replace the original pack's button behavior. Repeated hits during the cooldown are ignored.

Native mode limitations

Native mode enables and saves Mortality, FriendlyFire, Knockout and a 20-second knockout length for the whole lobby. Only the stabbed player receives the damage request, but the rules affect other combat too. Previous settings are restored on mode exit, disconnection or normal shutdown, not after a crash. Settings left by older versions remain the starting values.

Immunity mods, game modes and incompatible versions may prevent the native effect. It is not guaranteed to work on every client. Fusion's knockout releases held objects and restores health on recovery.

Manual installation

Place FusionSyringe.dll in BONELAB/Mods. Remove any old copy before replacing it. Install the separate syringe content pack through. Do not install the disabled development DLL.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
