To ensure smooth performance as your zoos grow, Planet Zoo: Console Edition features a Zoo Complexity Meter.
The Zoo Complexity measures the total sum complexity of all elements in your zoo. This includes animals, habitats, scenery, facilities, paths, and lakes. If your zoo reaches 100% complexity, you will no longer be able to add any new elements and animal breeding will be disabled until your zoo's complexity is reduced.
