Getting enough heatstamps in Frostpunk 2 can be a bit of a challenge. This new resource represents a currency grounded in heat—that's right, things have gotten so bad in the eternal winter that New London has started monetising warmth and exchanging it for goods and services. You'll need heatstamps to do just about anything; from building a district to researching new tech in the ideas tree.
Unlike prefabs, there are a very limited number of ways to get them, however, and most of these revolve around Frostpunk 2's faction mechanics. Apart from workforce, getting enough heatstamps is your most significant challenge in terms of expanding the city and making progress in resolving its many problems.
