Each map is procedurally generated (at least insofar survival mode is concerned) basing on a specific theme. These can offer unique terrain features or special gameplay rules.
List of themes[]
- The Dark Moorland: In the Dark Moorland, the terrain is very intricate as it forms gorges and small plains. Small rivers and pools can be useful terrain against the infected but will make the colony much harder to expand.
- The Peaceful Lowlands: Surely, you will think at first sight that the Peaceful Lowlands is a nice place to settle a colony. But that is the same thought that many people of the past had a long time ago until the infection spread to their villages. Now there are many Doom Villages threatening these peaceful lands. Be careful with them.
- The Frozen Highlands: In the Frozen Highlands, the big mountain ranges reach the sky. Between the mountains, there are vast frozen valleys and lakes. The cold can be your worst enemy. Buildings require more energy to keep them warm and units walk slower. The good news is that the infected activity is much lower because of the cold.
- The Desolated Wasteland: Without a doubt, this is a terrible place to found a colony. Although these arid lands have much more mineral deposits and oil than any other terrain, the land is very open therefore the visibility distance is very high. Lots of small colony groups have died in this dry land. What's worse, the infected seem much more active under this warm climate.
