Petrichor: Cows, the final expansion, adds COWS to the mix, bringing with it:
- The new Graze Action allows players to move the cows, produce manure, manipulate methan crystals and effect the world's climate.
- The Climate Board tracks the climate and related events.
- And a whole new set of Climate Sensitive Trees: The Norway Spruce, The Date Pal, The Sweet Chestnut, The Baobab.
The Cows Expansion is compatible with both the Honeybee and Flowers expansions and supports Southern Winds solo mode.
