Zoo Tycoon 4

In April 31, 2016, Zoo Tycoon 4 is the sequel to Zoo Tycoon and Zoo Tycoon 2.

Originally released for Microsoft Windows, Zoo Tycoon 4 is also available for the Playstation 4 and Xbox One.

Gameplay
Zoo Tycoon 4 has three modes of play: Freeform mode, Challenge mode, and Campaign Mode.

Freeform mode allows the player to create a zoo of limited space with no restrictions. The player is given an unlimited money supply and every animal is available. All objects, except the ones yet to be unlocked in campaign and challenge games, are available.

Challenge mode is very similar to freeform mode. The player chooses the initial amount of money available; players must earn money through donations. There is initially a limited amount of animals and objects. As the zoo increases in fame, more animal species and objects will become available. Many objects must be researched before they can be purchased. In this mode, the player is given tasks that must be included. These include pleasing a celebrity guest, or photographing an animal's behavior. The reward for completing these challenges could be an in-game award or cash grant, and may also unlock themed objects for use in freeform mode.

Campaign mode involves the player receiving a specific goal, and the completion of the goal allows the player to go on to a harder challenge. If all the scenarios are completed, objects become available for purchase in freeform mode.

Game Mechanics
The Zoopedia, an encyclopedia on the entire game and all of its objects, will give the player information about anything in the game. Animal's dietary habits, compatibilities, preferred habitats, real-world and in-game behaviors, for example, are noted on the Zoopedia.

Animals each have their own biome that they belong in. A biome is an important feature in the game, as an animal in an unsuitable habitat will quickly become unhappy. Biomes include alpine, boreal forest, desert, grassland, savannah, scrub, temperate forest, tropical rainforest, wetlands, and tundra.

As a player's zoo becomes more popular, the zoo will increase its fame rating. Accessible pathways, a wide variety of happy animal species in well-kept exhibits, guest activities all play a role in the guests' enjoyment of the zoo.

Animals
There are said to be more than animals on the Playstation 4 and Xbox One versions.
