Terra Nil: How to Unlock All Animals

Here's how to discover and find all Terra Nil animals in the game's four biomes.

Unlocking Terra Nil animals is an essential part of reclaiming the wastes. As you cleanse the toxins poisoning the land and water, reintroducing fauna is a required part of rehabilitating your map. So how do you discover animals?

Each Terra Nil biome has a different collection of unlockable animals, and each of those fauna species has specific unlock requirements. The game doesn’t outright tell you what these requirements are, but there are hints in your Handbook under the animals tab. 

Some fauna types, like the Bear, require forests before they can be discovered. Others, like Narwhal require something different. 

To discover animals, you must reach the third stage of biome rehabilitation, after you’ve had the chance to regrow all of a map’s various ecosystems and build certain structures. Once you do, you’ll get access to the scanner, which you can build anywhere and use to scan the map and its ecosystems for animals. 

Click the arrow under the animal footprint that appears in the top left corner of the screen, then click each animal portrait. Then click the orange circle just below the portraits to the right, and highlight an area of the map to scan for them in that area. 

Below, we’ve outlined the animals in each biome, including their discovery requirements. It’s possible that you won’t be able to discover all fauna types on a single map because of the requirements and tile sizes of ecosystems.

How to Find All Animals in Terra Nil

To effectively scan for the animals below, you’ll typically need to scan multiple tiles across several biomes at the same time. For example, you can simply scan 20 greenery tiles for Deer, but you’ll need to scan 20 river tiles and 10 forest tiles with the same scan to discover Beavers. 

Further, some animals require specific weather conditions or you create lakes to find them. Most criteria are self-explanatory, but we’ve left notes on those that are a bit more confusing.
