Let’s Build a Zoo: Technology Guide (All Tech Tree)

A guide for the technology tree in Let’s Build a Zoo

 

Introduction
This is a guide for the tech tree. In this game, the tech tree is shown progressively as you unlock techs. You can only see directly next to the techs that you’ve unlocked–save for a few specific ones. This makes it difficult to find a tech if you say, want to unlock 2 researchers, as they do not follow distinct and separate branches. To get a researcher, you have to go down the biome path or down from the Nursery path. Examples like this are all throughout the game, so I hope to help people find out which research is actually important to them based on their goals in the game.

This guide is basic information complete, but I will edit later for better formatting and to add more information on specific techs.

  • Part 1 [Full Tree] Shows images of the full tree with highlights based on specific types of tech
  • Part 2 [Descriptions] Has the information on cost and description of the tech.
    • Format: The number of the tech going from left to right – [Research cost] Name – description and requirements (if applicable)
    • Naming Convention: 1-8d, 1-8u. D means down. U means up. Starting from the first two lines you have access to when starting the game.
