Tech tree

One of your long-term objectives is to unlock new technologies from the five branches of the tech tree. In the aftermath, much of mankind’s knowledge was either lost or outright destroyed. Fragments can still be recovered from various locations on the world map to aid the colony. The research locations can be searched for Science points which, unlike other resources, are immediately available for the colony. And the bigger your specialists' research skill is, the faster they can extract all the usable knowledge a particular location has to offer.

Branches

Science points can be spent to unlock technological advancements in the tech tree, which is divided into five branches:

• Colony adds to your housing and general colonist potential.
• Food offers both improvements to production speeds and completely new forms of cultivation and animal breeding.
• Exploration improves your efficiency and possibilities on the World Map while also increasing the settlement's security.
• Production increases production capabilities and unlocks new structures.
• Resources increases advanced resources production and extraction.

As a general rule of thumb, the further down the tree a particular advancement is, the more it costs, so always keep an eye on museums, old radar stations and observatories while exploring the map. Science is what takes your colony to the next level from just surviving into getting back what was lost.

Categories

Each researched technology offer one of eight unlock effect types. These can be determined at a glance by the tech frame's top color and are as follows:

• Building unlock - Unlocks a new building.
• Building upgrade - Unlock a building's upgrade option.
• Decorations - Create a more charming environment.
• Durability - Improves buildings' protection against natural deterioration or elements like cold or Pollution.
• Efficiency - Improves the speed or amount of production.
• Ideology - Special improvements based on your chosen ideology (hardy survivalist, colony builder, wasteland explorer).
• People - Affects or improves people's lives and Happiness.
• World map - Enhances actions on the World Map.

List of technologies

Colony

	Technology			Type	Unlockables	Prerequisites	Description
	Heavy Tarps	15h	50		+40% Durability to: Emergency Shelter Tent	N/A	It's not much in terms of comfort, but making the tarps in tents more rigid gives them a bit more strength and lessens the feeling your home might fly off at a modest breeze.
	Nurses	15h	75		+1 Work slots to: Medical Tent	N/A	Shared duties and clear communication in life-threatening situations are paramount, so colonists are treated quickly and correctly.
	Weatherproof Seams	15h	25		−3 Repair cost to: Emergency Shelter Tent	Heavy Tarps Hardy survivalist	Learning to do seams that hold up in the rain, snow or meteor storm means tents and emergency shelters can be repaired with small patches instead of replacing entire sections.
	Medical Training	15h	50		+15% Healing speed to: Medical Tent	Nurses	Without a steady supply of medicine and medical equipment, people have to rely on simple, straightforward methods of healing. Learning about these is key in keeping your population safe.
	Remembrance	18h	100		Memorial	Either: Heavy Tarps Nurses	Remembering those who are gone is painful, but it is the only way forward. A Memorial allows people to light a candle for those who did not survive the aftermath.
	Education	21h	120		School	Remembrance	Educating future generations at Schools is more important than it has ever been. Educated children gain a permanent Educated trait if they go to school long enough. Education makes them more efficient members of society once they start working.
	Simple Decorations	15h	25		Tiny Pink Flowers Tiny White Flowers Red Flowers White Flower Bush Green Tree	Education	A modest selection of decorations to cheer up your modest Colony.
	Aggression Release	1d 3h	150		Arena	Education	For some, the way to relax is to get punched in the face or see someone else knocked silly. The Arena allows Colonists to brawl and let off some steam while others enjoy the carnage from the stands. Perhaps not civilized, but it sure is fun!
	Pavement	15h	50		Paved Road	Aggression Release	Caesars and pharaohs figured stone-paved roads were the way to bring a bit of civilization to a settlement—and keep their sandals clean. Faster movement on Paved Roads.
	Cleansing	1d 11h	200		Sauna	Aggression Release	Hygiene in the post-apocalypse seems like a minor thing to worry about. Yet, if completely forgotten, it will lead to diseases that would have been easily prevented with a nice shower and a bit of socializing in a hot Sauna. Saunas require Firewood to function.
	Elegant Decorations	15h	50		Small Green Bush Tall Green Bush Lantern Bottle Tree Paper Windmills	Cleansing	A reasonably elegant set of decorations to jazz up your growing Colony.
	Medical Center	1d 20h	250		Field Hospital	Cleansing	There is no way to keep a large colony healthy with a simple Medical Tent. A properly managed Field Hospital is both more spacious and effective in treating a wide variety of conditions. Requires access to a Water Tower.
	Prescriptions	1d 3h	150		+25% Healing speed to: Field Hospital	Medical Center	It's rather likely medics will be treating the same people over and over in the aftermath. Knowing and keeping track of patients helps give them the right treatment faster.
