Mutators are special game rules that change how the game works – for example only allowing pistols, adjusting health, changing movement speed or adding special effects like "Vampirism". The game ships with a range of built-in mutators; some mods add their own.

Enable mutators

  1. Open dashboard
    Open the dashboard of your server.

  2. Open settings
    Navigate to the Settings.

  3. Enter mutators
    Enter the desired mutator in the Additional Parameters field:

    -Mutators=MutatorName
    

    Separate multiple mutators with commas:

    -Mutators=Vampirism,HotPotato,PistolsOnly
    
  4. Restart the server
    Save the setting and restart your server.

Configuring mutators (advanced)

Some mutators can be customized further via Engine.ini (in the folder Insurgency/Saved/Config/LinuxServer/). Add the respective header and place the settings below it.

Headshots Only

[/Script/Insurgency.Mutator_HeadshotOnly]
bCheckMeleeDamage=false

bCheckMeleeDamage (default false) – whether melee hits count as headshots.

Hot Potato

[/Script/Insurgency.Mutator_HotPotato]
bIgnoreHeadshots=false
bBotsOnly=false

bIgnoreHeadshots – don't drop a grenade on a headshot kill. bBotsOnly – only trigger for bots.

Vampirism

[/Script/Insurgency.Mutator_Vampirism]
bCountFriendlyFire=false
MaxHealth=1000

bCountFriendlyFire – count friendly fire towards health gain. MaxHealth (default 1000) – maximum health you can gain from dealing damage.
