Frontier Developments released Planet Zoo on 5 November 2019 with 73 animals in the base game, well past the 50 originally promised. Four modes ship together: Career, Franchise, Challenge and Sandbox, with Franchise running on Conservation Credits earned by releasing well bred animals back to the wild. Career runs 12 scenarios, opening at Goodwin House and closing at the Bernie Goodwin Memorial Zoo in Upper Bay, New York.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Welfare from nutrition, social and suitability
Each animal scores welfare from access to food and water, social health covering group size and sex balance, and habitat suitability covering terrain types, temperature, plant cover and enrichment. Every enrichment tier you research pushes that score closer to 100 percent.
Conservation Credits from releasing animals
Releasing an animal to the wild converts it into Conservation Credits, the currency Franchise mode is built on. Release healthy adults with high fertility and a high star rating, because juveniles and elderly animals return far fewer credits.
Research at the Research Centre
Vets research animal species and mechanics research facilities and habitat items, both from a powered Research Centre with access to the relevant habitat. Research unlocks higher enrichment tiers, better medical treatment and reduced running costs.
Barriers and terrain shaping
A habitat needs an unbroken barrier the occupant cannot climb, jump, dig under or smash, and each species tests differently. One way glass keeps nervous animals calm while guests still get a view, and terrain tools set the grass, sand, rock and water ratios each species expects.
Guest education and donation bins
Education boards, speakers and Zoopedia entries raise guest education, and educated guests donate more at bins. A donation bin beside a well presented viewing area out earns most food and drink shops in the same footprint.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Zookeeper | Feeds animals, cleans habitats and handles enrichment items. | Every habitat, with roughly one keeper covering two or three nearby enclosures |
| Veterinarian | Treats sick animals, handles contraception and runs species research from the Research Centre. | Disease management and unlocking higher enrichment tiers through research |
| Mechanic | Repairs generators, water pumps and rides, and researches facility improvements. | Power and water infrastructure, plus facility research at the Research Centre |
| Caretaker | Empties bins, cleans paths and restocks vending machines. | Guest areas, particularly around entrances and food courts |
| Security Guard | Deters vandals and responds to escaped animals. | Large zoos with high guest counts and habitats holding dangerous species |
Zookeeper: Feeds animals, cleans habitats and handles enrichment items. Keepers are the staff you always need more of, and their work zones should be drawn tightly rather than spanning the whole zoo.
Veterinarian: Treats sick animals, handles contraception and runs species research from the Research Centre. A vet or a caretaker is required before you can put any animal into a habitat at all.
Mechanic: Repairs generators, water pumps and rides, and researches facility improvements. Ignore mechanics and a power failure will take out the climate control keeping tropical species alive.
Caretaker: Empties bins, cleans paths and restocks vending machines. Guest happiness drops quickly on a dirty path, and unhappy guests donate less at the bins you placed for income.
Security Guard: Deters vandals and responds to escaped animals. Escapes are usually a barrier problem rather than a security problem, so guards are a safety net rather than a fix.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Goodwin House | Career scenario 1, tutorial | Core building tutorial, first animal handling, introduction to the Goodwin story |
| Panda Park | Career scenario 3, tutorial | Breeding and welfare tutorial, research introduction, conservation basics |
| Maple Leaf Wildlife Park | Career scenario 4 | Cold biome practice, larger budget management, first non tutorial objectives |
| Great Caldera Safari Park | Career scenario 5 | Safari layout practice, African species roster, terrain problem solving |
| Bernie Goodwin Memorial Zoo | Career scenario 12, finale | Campaign completion, full system test, gold star Career achievement |
Goodwin House: The opening Career scenario, Stately Home Schooling, built around the Goodwin family estate. It teaches habitat construction, staff hiring and guest paths one objective at a time.
Panda Park: The third tutorial scenario, Bear Essentials, centred on giant pandas. Pandas are demanding on habitat and breeding, which makes them a pointed lesson in welfare before the campaign opens up.
Maple Leaf Wildlife Park: The Eye of the Taiga scenario in Canada, bordering Candy Lake. Cold climate species and taiga terrain replace the temperate defaults of the tutorials.
Great Caldera Safari Park: The Go to Crater Lengths scenario, an African safari park built in and around a crater. Terrain constraints force layouts that do not work anywhere else in the campaign.
Bernie Goodwin Memorial Zoo: The Last Leg, the twelfth and final Career scenario, set in Upper Bay of New York. It expects competence in every system the previous eleven taught and closes the Goodwin family story.

Tips That Actually Matter
- Research enrichment tiers before you buy expensive animals. A species sitting in a habitat with tier one enrichment will never reach acceptable welfare, and welfare drives everything from breeding to Conservation Credits.
- Draw keeper work zones tightly around two or three neighbouring habitats. A keeper assigned across the whole zoo spends most of the day walking rather than feeding.
- Donation bins placed at habitat viewing areas earn more than most shops of the same footprint, because educated guests donate more. Pair every viewing platform with a bin and an education board.
- Check the barrier a species can defeat before you build. Climbing, jumping, digging and strength are tested separately, and an escaped animal is almost always a barrier chosen without reading those numbers.
- One way glass keeps nervous species calm while guests still see them. It costs more than plain glass and it is the difference between a shy animal hiding all day and being visible.
- Release adults, not juveniles or elderly animals, and check their star rating first. The higher the rating, the more Conservation Credits the release returns in Franchise mode.
- Keep a Quarantine facility from the start. Disease spreading through a breeding group destroys weeks of genetics work and quarantine is far cheaper than the vet bills that follow.
- Power and water are physical networks in Planet Zoo. Place a generator and pump within reach of new construction before building, because retrofitting infrastructure through finished paths is tedious.
- Breed for genetics rather than headcount. Size, longevity, fertility and immunity all carry into the offspring, and a pair of strong parents produces animals worth far more on the Animal Market.
- The Australia Pack, released 25 August 2020 with Update 1.3, added the Koala, Red Kangaroo, Dingo, Southern Cassowary and Eastern Blue-Tongued Lizard, plus the Tanami Roadside Zoo challenge. Check which pack an animal belongs to before planning a themed area around it.
Common Mistakes to Avoid
- Buying rare animals before researching the enrichment tiers their welfare depends on.
- Building a barrier without checking whether the species can climb, dig or smash through that specific type.
- Assigning every keeper to the whole zoo instead of tight work zones, so nothing gets fed on time.
- Releasing juveniles or elderly animals to the wild and wondering why the Conservation Credit return is so low.
- Skipping donation bins and education boards, then running at a loss while blaming ticket prices.
Frequently Asked Questions
How many animals are in the Planet Zoo base game?
Seventy three at launch on 5 November 2019, despite Frontier initially stating fifty. Later DLC packs added more, including the Australia Pack in August 2020.
What is the difference between Franchise and Sandbox?
Franchise runs on Conservation Credits earned by releasing animals and connects to an online Animal Market shared with other players. Sandbox gives unlimited money and no constraints, so nothing you do there feeds the credit economy.
How many Career scenarios are there?
Twelve, starting with Stately Home Schooling at Goodwin House and finishing with The Last Leg at the Bernie Goodwin Memorial Zoo in Upper Bay, New York. The first three are tutorials.
How do I earn Conservation Credits quickly?
Breed animals with high fertility and star ratings, keep welfare at 100 percent, and release healthy adults to the wild. Star rating drives the payout, so genetics work matters more than volume.
Why do my animals keep escaping?
Almost always the barrier. Each species is rated separately for climbing, jumping, digging and strength, so check those figures against the barrier type and height before you finish the habitat.
