Planet Zoo 2 New Features: Aquariums, Aviaries & More

Everything new in Planet Zoo 2: buildable aquariums with sharks, walk-through aviaries with flying birds, Wildlife Reserves, the Animal Brain and better building.

Planet Zoo 2 isn’t a graphical refresh — it adds the two things the community spent seven years asking for (real aquariums and real flying birds) plus a genuinely new idea: Wildlife Reserves that take your conservation work outside the zoo walls. Game Director Gareth Hughes calls it “Frontier’s most advanced zoo simulation.”

Here’s every confirmed new system, and how each changes the game.

Diagram of Planet Zoo 2's three new systems: aquariums with fully aquatic species, aviaries with fully flying birds, and Wildlife Reserves where released animals keep breeding.
Sea, sky and the world beyond the fence — the sequel's three new pillars.

Aquariums: the franchise first everyone wanted

For the first time, you can build custom aquariums housing fully aquatic species — sharks, rays, turtles, and shoals of fish. Confirmed inhabitants already include the Blacktip Reef Shark, Indo-Pacific Leopard Shark, Hawksbill Turtle, Ocean Sunfish and Red Lionfish.

The simulation depth goes beyond decoration:

  • Tanks can be freshwater or saltwater
  • Filtration systems must keep water clean
  • Keepers dive into tanks for animal care
  • Underwater tunnels let guests walk through your exhibits
  • Water reacts dynamically to movement — including ripples when land animals wade in

In Planet Zoo 1, aquatic life meant small exhibit boxes. This is a different category of feature.

Aviaries: birds that actually fly

The second franchise first: fully flying birds with complete 3D navigation, housed in aviaries you build yourself from barriers, support poles and mesh or glass covers. Support poles generate dynamically as you shape the roof, cover sag is adjustable, and guests can walk through suitable aviaries.

Confirmed birds so far include the Toco Toucan, Secretarybird, Great Hornbill, Long-eared Owl, White-tailed Sea-Eagle and — a franchise debut that delighted the community — the Shoebill. Birds nest, cohabit with other species, and adapt to environmental changes. Hughes has called them “the most challenging animals we’ve ever made.”

Wildlife Reserves: conservation beyond the zoo

The most conceptually new system. Meet conservation requirements and you can release animals into fully customizable Wildlife Reserves around the world — the reveal showed a Scottish Highlands reserve, previews an African one. Released animals aren’t a one-way donation either: they keep breeding in the reserve as long as they’re happy, extending your conservation loop indefinitely. Reserves connect to the FEN network for rewilding and research, and you can visit them.

For a series whose whole identity is conservation messaging, making “release to the wild” an actual gameplay loop rather than a menu button is the smartest addition in the sequel.

The Animal Brain and the Living UI

Under the hood, animals run on a new “Animal Brain” behavior system — Frontier’s framing is “a generational leap” in animal detail. What you’ll actually notice:

  • Living UI: animals visibly display moods and needs — a thirsty animal looks thirsty — instead of burying everything in menus
  • Herding behavior, grazing on vegetation you plant, expressive emotions
  • Smarter climbing (animals can act while on beams), jumping, and scratching/rubbing on any suitable surface rather than only designated enrichment items
  • Seasonal breeding with visible pregnancy

Building and management upgrades

The construction toolset gets quality-of-life work throughout: a circular plaza stamp for fast path building, open-plan buildings for restaurants and facilities (no more walled boxes), improved verticality, expanded terrain editing, nature brushes, resizable scenery, and ready-to-place blueprints alongside piece-by-piece building. Frontier says tools are simplified for casual players without losing depth for advanced builders — the eternal balance claim, but the plaza tool and open-plan buildings address two real PZ1 friction points.

Four new scenery themes ship at launch alongside five returning ones, and the Cobra engine gets a new global illumination system, better fur shaders and realistic water.

What this all adds up to

Planet Zoo 1 was already the genre’s benchmark; the sequel’s pitch is breadth — sea and sky added to land — plus a conservation endgame. The open questions that remain (launch animal count, PZ1 content carry-over, post-launch DLC plans) are tracked in our modes & FAQ page, and the full species list so far is in our confirmed animals list.

Frequently asked questions

What's new in Planet Zoo 2 compared to Planet Zoo 1?

The headline additions are fully aquatic species in buildable aquariums, fully flying birds in customizable aviaries, and Wildlife Reserves that extend conservation beyond the zoo — plus a new Animal Brain behavior system and rebuilt construction tools.

Does Planet Zoo 2 have aquariums?

Yes — a franchise first. You can build freshwater or saltwater aquariums with sharks, rays, turtles and fish shoals, complete with filtration management, diving keepers and underwater viewing tunnels.

Can birds fly in Planet Zoo 2?

Yes. Birds have full 3D flight and navigation inside customizable aviaries with glass or netted covers, and guests can walk through suitable aviaries.

What are Wildlife Reserves in Planet Zoo 2?

Once you meet conservation requirements, you can release zoo animals into customizable Wildlife Reserves around the world, where they continue to breed as long as they're happy.
