Technology Tree

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

Description[edit | edit source]

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.

Unique Technologies[edit | edit source]

Unique technologies refer to technologies that are exclusively available or unavailable depending on the scenario played. These include the following:

Exclusively Available[edit | edit source]
Exclusively Unavailable[edit | edit source]

Some other techs can be randomly unlocked by scouting locations in different scenarios, if said locations offer tech drops.
