In Frostpunk 2, heatstamps are a critical resource derived from warmth, essential for city management, construction, and technological advancement. Players can obtain heatstamps through various strategies, including:
- Taxing the population to generate a weekly income, contingent on meeting their goods demands and establishing an industrial district.
- Using the Raise Funds action with factions, which has a cooldown of about 40 weeks, to gain significant heatstamp contributions while managing faction relations.
- Employing the Demand Funds action to forcibly acquire heatstamps, requiring guard squads for enforcement.
- Requesting heatstamps from supportive factions during rallies for a one-time contribution.
- Passing laws that increase heatstamp income per capita, such as Paid Essentials, while being cautious of laws that may reduce heatstamp generation.
