About Pet Companions
From Factorio Mod PortalA pet that lives in your factory. It follows you, settles when you stop, fetches a thrown ball, warns you of biters, learns tricks and keeps a journal of everywhere you have been together. Pick your kitten's coat from 14 and name it. There are 12 species and 65 coats. All are found, rescued or bred. Build a kennel, whistle it to heel, feed it, and raise it over 90 hours. It can never be lost. Space Age optional.
Early development.
There are no technologies in this mod. It does not alter anything in the base game or Space Age. It only adds a couple of items and features, and can be safely added to any save, and should be safe to remove at any time. Just grab your stuff from the pet inventories first.
A pet that
- grows up and levels up
- follows you
- settles when you stop
- fetches a thrown ball
- warns you of biters
Contains cats, dogs and one secret pet to unlock at end-game.
Twelve species and sixty-five coats.
The pets are found, rescued and bred.
You will start with one pet and discover more as you play.
Pets have different abilities, varying with species.
- Different species have different trunk sizes and different equipment grids.
- Cats can stealth and sneak up to enemies undetected, but have the smallest trunk and equipment grids.
- Some dogs can carry more, but have smaller equipment grids, while others the oposite.
Send your pet on missions, use them to assist you with roboports, use them to discover areas on the map, send them to fellow players with a gift in the trunk.
Keep the pet happy with pet food, crafted from biomass which now drops from enemies, and later can be crafted from fish in a bio-chamber.
A pet with good mood will receive a small movement bonus. Watch the pet "emotes" to check its mood.
A wounded pet will become hungry. Give it food to heal faster. Feeding the pet is not a chore, if the pet is healthy.
The top level pets will be close to a legendary spidertron in equipment grid size, but do not carry rocket launchers, and serve a different purpose.
Feedback is appreciated.
