How Does It All Work?

To get started, simply go to the UTILITY menu of the CHEMLAB and craft the free settings holotape. The mod starts in a disabled state, so you will need to use the holotape to turn it on and to set up the basic settings for the mod. For those who use MCM, the mod does ship with an MCM menu for you to use instead of the holotape, though you aren't required to use it (and you aren't required to use MCM for those that don't).

The difficulty setting in the holotape tells the infestations how big they are and what relative strength the ferals are. The higher the difficulty, the more ferals there will be and they will be of stronger stock.

To clear an infestation, all ferals at the target site must be eliminated, lest the infestation continue to grow. Missions for infestations show as MISC quests and will not clutter your main quest log.

After each infestation is cleared, it allows for further infestations to occur, allowing the mod to last for as long as you play your character.

Failure to clear infestations will result in the fully formed, level 3 infestation leaving their current lair and making their way to the nearest owned player settlement in search of food, which of course is what makes the mod's infestations have an actual gameplay hook. Works best when you have mortal settler mods enabled, so there is an actual cost to NOT clearing infestations.

Infestations randomly occur as you travel around the Commonwealth worldspace; they will never trigger in Far Harbor or Nuka World.
