BUILD THE BIOLOGICAL DYNASTY Critterra is a Bio-Historical City Builder where civilization is defined by the collision of human history and animal biology. (Biology defines economy) You don't just build a city; you manage the metabolic and evolutionary imperatives of your species.

THE FOUNDATIONAL SEVEN Launch into Early Access with 7 distinct civilizations, each with unique biomes and mechanics:

• The Otterman Empire: Master hydraulic engineering and coffee trade in the wetlands.

• The Bearvarians: Deep forest brewers who rely on fermentation and hibernation cycles.

• The Catztec Empire: Vertical jungle architects fueled by solar tribute.

• The Mongrel Khanate: Nomadic logistics experts who move their cities with the seasons.

• The Mink Dynasty: Masters of rice paddies and water management.

• The Nor-Steeds: Coastal raiders who leverage fjord economies.

• The Babylions: Builders of hanging gardens and complex law codes.

EVOLUTIONARY GAMEPLAY

Serendipitous Overlap: Mechanics are derived from biological reality. A "Spaniel" faction isn't just a dog in a helmet—it utilizes the "Flushing Instinct" for stealth detection.

Metabolic Economics: Your citizens are not static units. They are homeostatic organisms that require thermal regulation, hydration, and specific sensory inputs to survive.

The Infinite Roadmap: Critterra is built to scale. Our design bible includes 35 additional civilizations arriving in 5 planned expansions, introducing mechanics like Systemic Warfare (Croco-nile) and Dynastic Genetics (Habs-badgers).
