How to Unlock the Idea Tree

Build a Research Institute

Frostpunk 2 Building Research Institute

After finishing the Prologue in Story Mode, you will gain access to building the Research Institute early on in Chapter 1. Building this on an Expanded Housing District will unlock the Idea Tree, which would be found on the bottom-right portion of the screen. You can also access the Idea Tree by pressing R once unlocked.

Radical Ideas Explained

Ideas Born by High Zeitgeist

Frostpunk 2 Radical Idea

When your level is high on a specific City Direction, certain Ideas will emerge based on that Zeitgeist. These will form Radical Ideas, which can be found on the Idea Tree as red-colored Ideas instead of the usual yellow. Fulfilling Radical Ideas will increase the City Direction level and the Relation of the Faction that the Idea is under.

Additionally, some Radical Ideas will boast the most expensive research costs out of the entire Idea Tree.

What is the Idea Tree?

Where Factions Propose Ideas

Frostpunk 2 Idea Tree

All Factions will present different Ideas in order to improve the City, within various categories such as Heating, Resources, Frostland, City, Society, and Hubs. Each Idea has different requirements in order to be implemented, with all of them costing a certain amount of weeks and Heatstamps. Implementing an Idea marked with a Zeitgeist will move the City Direction towards that Zeitgeist. In turn, it can also affect the Relations of Factions.

List of All Factions

Unlocks Buildings

Frostpunk 2 Building Unlocked

Majority of Buildings are locked behind the Idea Tree, many of which provide helpful upgrades and features to the City and its Districts. Do take note that constructing some of the Buildings will affect the Relations of Factions and the City Direction.
