BONELAB Fusion Killer Mode

Killer Mode is an experimental asymmetric horror gamemode for BONELAB Fusion. One player becomes the Killer while everyone else becomes a Survivor. Survivors must hide until the timer ends or escape through a timed exit while the Killer hunts them.

The main purpose of this mod is to help Fusion hosts create and host horror games on ordinary or custom BONELAB maps. The host can place saved spawns, spectator areas, escape doors, and objectives directly in-game without using Unity, then configure the roles, equipment, atmosphere, timers, and round rules from BoneMenu.

Requirements

• BONELAB on Windows PC
• MelonLoader 0.6.x
• BONELAB Fusion 1.14.2
• BoneLib 3.2.2
• The same Killer Mode version installed by every player

Thunderstore Mod Manager or r2modman installs Fusion and BoneLib automatically. Killer Mode is a code mod, so joining a Fusion lobby does not automatically download it. Every player must launch the same mod profile before joining.

Main Features

• Host-authoritative Killer, Survivor, and Spectator roles
• Survival and Escape game modes
• Random, host, or rotating Killer selection
• Custom Killer avatars, weapons, Survivor weapons, flashlights, and smoke grenades

• Countdown, round-start, Escape Door, private Survivor Escaped, final-seconds, Last Survivor, round-end, and heartbeat sounds
• Last Survivor location reveal visible only to the Killer
• Spectator-only voice chat
• End-of-round leaderboard broadcast to every player, with mode-specific Survival or Escape results
• In-game map setup tools and a separate Map SDK for map creators

Installing and Starting

1. Install this package with Thunderstore Mod Manager or r2modman.
2. Give every player the same Thunderstore profile or package list.
3. Launch the modded game and create or join a Fusion lobby.
4. Load a playable level. The BONELAB Hub is not treated as a playable Killer Mode map.
5. Open the Fusion menu and go to Gamemodes.
6. Select Killer Mode.
7. Open the BONELAB menu, select BoneMenu > Fusion Killer Mode, and configure the roles, equipment, round rules, and map positions.
8. Select START ROUND NOW, or use Fusion's automatic round countdown.

For manual installation, copy BONELABFusionKillerMode.dll from this package's Mods folder into the BONELAB Mods folder. Fusion and BoneLib must also be installed.

Roles and Objectives

Killer

The Killer sees a red YOU ARE THE KILLER - KILL ALL SURVIVORS message. Survivors receive a configurable head start, during which the Killer is held at the Killer spawn and cannot attack. When the Hunt begins, the selected weapon spawns and the Killer can move.

Eliminate every living Survivor before the timer reaches zero. In Escape Mode, stop Survivors from reaching the green Escape Zone after the door opens. The host can configure Killer health, speed, mortality, and whether Survivors can damage the Killer.

If the Killer loses the weapon, the host can use RECOVER LOST KILLER WEAPON after the Hunt begins. A short cooldown prevents accidental repeated spawning.

Survivors

Survivors see a green YOU ARE A SURVIVOR - HIDE OR ESCAPE message. Their inventory can be cleared when the round starts, and selected flashlights, smoke grenades, or optional Survivor weapons spawn at the cyan Survivor circles.

• In Survival Mode, stay alive until the timer reaches 00:00.
• In Escape Mode, wait for EXIT OPEN, then physically enter the green Escape Zone before time runs out.
• Escaping is individual. An escaped Survivor keeps the win even if another Survivor remains behind.

Last Survivor

When only one living Survivor remains, the Last Survivor announcement and horror sound play. Only the final Survivor hears the looping heartbeat. The heartbeat becomes faster during the final seconds.

If enabled by the host, the Killer periodically sees the final Survivor's location through walls for a short time. The reveal does not show a health bar and never activates while two or more Survivors remain.

Spectators

Eliminated players, escaped players, and late joiners become Spectators until the next round. Spectators cannot fight, grab active round items, or enter an Escape Zone.

Spectators have a private voice group. They can speak with other Spectators, but the Killer and living Survivors cannot hear them, and Spectators cannot hear the living players.

Selecting the Killer Avatar

The host can use the current player avatar or force a built-in Strong, Heavy, Fast, or PolyBlank avatar. To select a downloaded avatar:

1. Wear the desired avatar in the Body Mall.
2. Open BoneMenu > Fusion Killer Mode > Killer.
3. Select USE MY CURRENT AVATAR AS KILLER SKIN.
4. The mode saves the avatar barcode and selects it for future rounds.

If another player becomes the Killer, Fusion can download the published avatar when that player has Download Avatars enabled and allows the required file size. If the avatar is missing or its download fails, Killer Mode safely uses PolyBlank for that round. Players cannot change avatars while a round is active, and their original avatar returns afterward.

Selecting Weapons, Flashlights, and Smoke Grenades

The easiest method is right-hand selection:

1. Spawn and hold the desired item in your right hand.
2. Open BoneMenu > Fusion Killer Mode with your left hand, then select Killer or Survivors.
3. Select the matching button:

• USE RIGHT-HAND ITEM AS KILLER WEAPON
• USE RIGHT-HAND ITEM AS SURVIVOR WEAPON
• **USE RIGHT-HAND ITEM AS SURVIVOR FLASHLIG
