Raise a family with children, experiment with genetic modifications, and command your own mechanoid army and workforce.

Raise a family

Have children and raise a family through natural or artificial means. Colonists could give birth or use a surrogate mother, take in a band of orphans, and even gestate embryos in machines. Play matchmaker with your colonists, or let their relationships grow organically. Prepare for labor and childcare, and get ready to welcome your little ones to the world!

Care for your babies

Keep your baby’s tummy full with lots of good eats, decorate an adorable nursery for playtime, and build a comfortable crib for a good night’s rest. Happy babies make for happy colonists.

Watch over your children

Give your children a rich and happy childhood by balancing their life between work and play. Help kids fulfill their learning desires by letting them explore nature, chat on the radio, spend time in class, daydream, scribble, and watch the grown-ups at work. Choose your children’s traits and passions at certain ages - the healthier their upbringing, the greater the variety of traits and passions to pick from.

Growth vats offer a cheaper alternative to normal child raising. Use vats to accelerate your children’s development to quickly churn out dumb soldiers and simple workers.

Genetic modification

Create your own genetically-modified colonists known as xenohumans. Curate a collection of exotic genes by purchasing them from traders, accepting them as quest rewards, or extracting them from your menagerie of xenohuman prisoners. Recombine genes to make bizarre and advantageous mixes of traits, and build your colony of xenohumans!

Meet new xenohuman factions

Engage with new factions consisting of exotic xenohumans. Xenohuman factions include hardy pig-people, poison-drinking waster pirates, unforgiving neanderthal hunters, and more. Factions feel different from each other - how you handle a group of frenzied fire-breathers will be different from stopping the wolf escorts sent by fur-bodied riflemen. Some xenohuman cultures are friendly, while others are hostile or prefer to be left alone.

Join the immortal blood-drinkers

Sanguophages pass among humans undetected while concealing superhuman powers and working to satiate their genetic need for blood. Powered by superintelligent nano-machines, sanguophages are ageless, immortal, preternaturally beautiful, and capable of launching deadly spines and healing allies. You may join their cult if deemed worthy, or force them to grant you immortality.

Build and control mechanoids

Make your colonist into a mechanitor - a person with a brain implant that lets them psychically command semi-living machines called mechanoids. Create mechanoids by growing them inside high-tech gestator tanks and command a wide variety of new combat and labor mechanoids.

Build a mechanoid army and experiment with a variety of battle tactics using swarms of cheap, disposable gunners, tanky defenders, shield-projecting snipers, flame-spitters, and more. At home, make mechanoid workers that can manufacture goods, rescue and tend to colonists, build and repair structures, sow and harvest crops, haul stuff, and other tasks. Grow your swarm and upgrade your mechanitor into an unstoppable mechlord.

Challenge super-mechanoid bosses

Call down three new super-mechanoid bosses to fight. Defeat these super-deadly enemies and their escorts and harvest special mechanoid chips from their smoking husks to advance your mechanoid technology.

Adapt to pollution

Your mechanoid infrastructure produces toxic wastepacks. Left unfrozen, waste deteriorates and leaks pollutants into the environment. Pollution poisons your colonists, mutates plants and animals, blocks the sunlight, and attracts giant hostile insects. Manage your waste, or embrace pollution with new gear, detoxifier organs, and genetic modifications.
