Maps

The maps in They Are Billions are quite small and full of zombies and villages of doom. Huge zombie swarms spawn at the edges from time to time and try to run your Command Center down. Currently there are four types of procedurally generated maps in the game, which are ordered in difficulty and need to be unlocked.

Types

Every type is build out of patches made of wood, stone and water as natural barriers. The ground is made of snow, sand or grass, which can influence some game aspects.

The Dark Moorland

The basic map, which is unlocked right from the beginning. Not a lot of free space, many small water patches.

The Peaceful Lowlands

Finish the Dark Moorlands on at least 100% to unlock. Has more space than the Dark Moorlands but the ground is only half grass, while the other half is made out of sand, on which you can't build farms.

The challenge is a tighter zombie population and more Villages of Doom, even right next to your starting location.

The Frozen Highlands

Finish the Peaceful Lowlands on at least 110% to unlock. This map is build like the Dark Moorland in winter. The infected are less agressive on this map meaning that noise and death of other zombies will atract less attention.

The challenge is a higher energy usage and all units are slowed due to coldness.

The Desolated Wasteland

Finish the Frozen Highlands on at least 140% to unlock. This map is build like the Peaceful Lowlands with more stone, iron and oil sources.

The challenge is a low number of grass ground required for farms and higher than usual zombie aggression resulting in food problems and large groups of zombies coming to investigate every kind of disturbance.
