Technology Tree

The Technology Tree is one of the Game Mechanics in Frostpunk.

Description
Upon construction of a workshop, engineers may be assigned to research and develop ideas on new buildings and technological improvements. Technological Improvement has the general effects of boosting exploration, improving insulation in the home/workplace, increasing resource gathering rates and upgrading the power/efficiency of heating sources. Technological development is crucial to building a viable city, sound planning and prioritization of technologies will prevent crises and allow a greater level of adaptation and manageability when challenges present themselves. Some technologies may be required to be researched in some scenarios to be able to finish objectives. Some technologies may also be 'found' or entirely absent depending on the scenario played.

The  Tech Tree  itself is presented visually (upon first workshop construction) to provide a high level of clarity regarding the interrelation of technologies and the order in which each 'branch' must be researched. In addition to this the tree is organised into tiers 0-5, the tiers must be unlocked by researching them and provide no direct benefits themselves but enable ever more advanced technologies to be acquired. The tiers function as an independent additional branch, requiring the previous tier to be unlocked. The following tree represents workshop tiers on the left side and techs unlocked by this tier are shown on the same row to the right of the tier mention. The following graph also displays the 4 tabs offered by the tech tree, each tab provides options and upgrades to different sectors of the city. The upgrades in each tab are unaffected by upgrades in other tabs although the tiers apply to the whole tree. Having multiple manned workshops will increase research rate but not necessarily in a linear fashion, using children as engineering apprentices will also provide an additional boost. Automatons may also operate a workshop non-stop if upgraded to do so.

Heating
This tech tab provides improvements to the Generator, Steam Hubs and Heaters.

Exploration & Industry
Options in this tree tab allows exploration of Frostland, as well as improving scouting, Outposts and the Factory.

Resources
This tech tab provides options to improve resources gather rate and workplace insulation.

Food, Health & Shelter
This tech tab provides improvements to food gathering, upgrading of shelter/medical facility insulation and the effectiveness of medical treatment.
