Embedded Files
Ever thought the animal rosters for the existing expansion packs needed a little spice, or that they were missing features? The Expansion Booster Packs are here to help, adding a variety of things to the game that mesh with and are treated as extensions of existing expansions.
African Adventure Booster Pack

African Adventure Booster Pack
October 22, 2025
African Adventure is light on a lot of things - it has animals, a campaign, some half-baked shelters and enrichment and some fancy new behaviors, but it plucks features and scenery from Endangered Species and parades them around as its own and doesn't have a lick of new foliage - its unlockable theme doesn't even come with a music rock!
This pack might not include new animals, but it does try to fill in some of AA's bigger holes, with 16 new foliage objects (8 trees and 8 smaller plants, some ported from Folksy Facelift and others brand new), a new scenery object in the Desert Music Rock, and a polished version of the unused Small Savannah Burrow (of the vanilla game's animals, only the warthog will use it, but any user-made animals with b_SmallSavannahBurrowUser="true" in their main .xml should be able to use it too).
3/28/2026 Update
Several of the plants should now appear more natural on sloped terrain. Please be aware that they will no longer appear if your Object Detail setting is set to low.
Tamboti trees and raffia palms can now be placed in shallow water, consistent with the other wetland trees.
Extinct Animals Booster Pack

Extinct Animals Booster Pack
June 21, 2021
This pack introduces three familiar Cenozoic mammals to the game: the colossal Columbian mammoth, one of the biggest mammoth species known to man; the dramatic Irish elk, bearing the biggest antlers of any deer; and the gnarly Embolotherium, an elephant-sized ungulate.
All three of these animals appear in Zoo Tycoon 2: Extinct Animals, albeit as cameos: the Columbian mammoth is an unlockable statue, the Embolotherium appears on a blurry plaque attached to the Extinct Education Center and the Irish elk has both a statue and a plaque.

A Deluxe Edition of the Extinct Animals Booster Pack, designed with the vanilla game in mind, is in development. Alongside the initial three animals (which will be a whole lot grander in stature in this package!), it'll feature a selection of new foliage, a handful of new fences and decor, and an alternate outlet for the Extinct Animals maps made for Folksy Facelift.

10/22/2024 Update
Fossils for the Embolotherium and Columbian mammoth may no longer be found during Level 1 of the fossil finding minigame, now requiring Level 3 and Level 5 to be uncovered respectively.
All three animals' biome preferences have been modified, reflecting version 1.1 of Folksy Facelift. Most heavy affected is the Embolotherium, which now lives in the Desert, Grassland and Savannah biomes (if you want to keep your pre-existing embolothere Scrub habitats, you might need to give them a couple more tar pits to keep their educational value up).
12/13/2022 Update
Embolotherium and Columbian mammoth fossils and cloning have been implemented.
A handful of subtle variants for the Embolotherium.
A small taste of Folksy Facelift behavioral changes, exclusive to the Columbian mammoths for now.
Columbian Mammoth / Imperial Mammoth
Mammuthus columbi / Mammuthus imperator
Only outclassed by the steppe mammoth in size, the Columbian mammoth (and Jefferson's and imperial mammoths, which were once regarded as their own species) is huge even by the standards of other elephants - perhaps twice as tall as a female Asian elephant and four times as heavy. Unlike the more famous woolly mammoths, which preferred extremely cold environments, Columbian mammoths could inhabit a variety of open habitats, from tundras to deserts.

Embolotherium
Embolotherium andrewsi
The embolotherium, hailing from Asia some 35 million years ago, has a very deceiving appearance. It looks a strange rhinoceros, with its bulky body and large, somewhat bifurcated "horn". In truth, it is, though a fairly close relative, not a rhinoceros at all, and its "horn" is an extension of its nasal bone, too fragile to be used as a weapon and probably used to enhance the sounds it made.

Irish Elk
Megaloceros giganteus
"Irish elk" is something of a misnomer. This giant deer is neither exclusively found in Ireland (it could be found across Europe in environments that were neither too hot nor too cold) nor an elk (it is most closely related to modern fallow deer.) Its greatest claim to fame is its mighty rack of antlers - together, an Irish elk's antlers could measure an astonishing 12 ft (3.6 m) across.

Ultimate Collection Booster Pack
May 25, 2025
Did you know that Zoo Tycoon 2's climactic compilation package, Ultimate Collection, might have been planned to have some extra content that didn't make it to the final release? The game files suggest that guests were meant to have a gate that they could use, and the old website advertises elephant seals as being in the package - no, really!
This pack offers standalone, lightly-updated versions of the southern elephant seal and guest gate that were made for Folksy Facelift. Keep in mind that FF's dedicated exhibit path and walkthrough exhibit feature aren't included here, just the gate!
Southern Elephant Seal
Mirounga leonina
They don't call this massive marine mammal an "elephant" seal for nothing - males have huge, bulbous, trunk-like noses that they use to amplify their roaring calls, like how an elephant trumpets. Equally deserving of the moniker is its size - a big male southern elephant seal can grow up to 20 feet (6 meters) long and weigh over 4 tons. They live in the Antarctic, the sub-Antarctic and on the southern fringes of South America, mostly feeding on squid and fish.
