Grassland - Navigate Through Storms
In the Grassland biome, prepare yourself for heavy storms, accompanied by rain, fog, and lightning. These weather conditions are random and will sporadically occur as you progress through the map. - Lightning Strikes: Not only do these add a visual spectacle, but they can also be dangerous for your city. Lightning can strike randomly across the map, causing damage to whatever it hits. - Spread of Fire: To make things more challenging, lightning strikes can ignite fires. These fires will spread and last for a certain duration, posing a risk to both units and structures in their path. Fire damage is currently mild, as there's no fire defense mechanism in place. We plan on evolving fire mechanics in future updates.
More about Fire
Fire will play a larger role in the game. Our plans involve allowing you to use fire as an additional defensive line by igniting a flammable surface, such as oil, just before the undead wave reaches you. One scene that comes to mind is the famous Battle of Winterfell in Game of Thrones, for those of you who have watched it:

Desert - Survive the Heat Waves
The desert biome has its own environmental obstacle: heatwaves. At any moment, the temperature can soar, affecting your workers' efficiency. - Adapting to Heat: You can counter the impact of heatwaves by crafting specific building upgrades—a refreshing mug of beer for your workers. This innovative mechanism will negate the adverse effects of the heatwave entirely for that structure.
Swamp - Tread Carefully Through Mud
In the Swamp biome, mud is the primary natural obstacle. Although it doesn't trigger like other events, mud patches are present right from the start. - Reduced Mobility: These mud patches slow down the movement speed of any unit—friend or foe—that crosses them. - Counteracting Mud: You can build roads over these patches to eliminate the slowdown effect. Road construction becomes a strategic necessity in this biome.
