Frostpunk, the post-apocalyptic survival city builder from 11 bit studios, has just been updated with a free DLC scenario.

Called The Fall of Winterhome, this new scenario tells the story of what happened to the titular settlement before the events of the main campaign. Featured above, you can view a new trailer for the content.

This mini-campaign introduces new mechanics, new buildings, and a new map that equates to several hours of content that expands upon the lore of the Frostpunk world. You can view the launch trailer above, and read the full patch notes here.

Here’s a rundown on the game, via 11 Bit Studios:

In an ultimately frozen world, people develop steam-powered technology to oppose the overwhelming cold. The city ruler has to manage both the inhabitants and the infrastracture the citizens live in. Leader’s tactical skills face challenges, frequently questioning morality and the basic foundation of what we consider an organized society. Here optimization and resource management often clash with empathy and thoughtful decision-making. While city and society management consume most of the ruler’s time, at some point exploration of outside world is necessary to understand its history and present state.

What decisions will you make so the society can survive? What will you do when pushed to the limits? And who will you become in the process?

Key Features:

• The City Must Survive
  Frostpunk is a city-survival game where heat means life and every decision comes with a cost.
• Maintain The Hope
  Survival is about hope and will to live. Your ability to spark and maintain these two in your people will be a determinant factor for success.
• Make The Law
  Society is a group of people abiding the same rules and sharing similar beliefs. Establishing laws and customs will be a crucial factor shaping your society.
• Weigh Your Choices
  Will you allow child-labour? How will you treat the sick and wounded? Frostpunk challenges a player’s tactical skills, while questioning one’s morality.
• Explore
  The world covers not only bits of the past but also the potential means to secure the future of your people.

Frostpunk will be available on Steam, GOG, and the Humble Store for $30.
