This is the base game required to play this DLC. Other expansions may also be required.
Bring the island to life with dynamic wildlife in Nucleares.
The Island Fauna DLC introduces a living ecosystem where animals roam freely, react to the player, and interact with each other. Smaller creatures will flee from danger, predators hunt their prey, and certain areas of the island become more dangerous to explore.
But the environment does not remain unchanged.
As conditions deteriorate, wildlife behavior begins to shift in unexpected ways. Familiar patterns break down, and the island can become far less predictable.
Dynamic wildlife system with multiple animal types
Natural behaviors: roaming, fleeing, and predator-prey interactions
Reactive world influenced by player actions and environmental conditions
Evolving animal behavior under extreme scenarios
