Zoo Tycoon 2 is a video game in which the player can create and manage a zoo by overseeing its finances, staff, and animal exhibits. The goal is to become a "zoo tycoon." Originally released for Microsoft Windows, Zoo Tycoon 2 is also available for mobile phones, Mac OS X, and Nintendo DS. It is the sequel to the 2001 game Zoo Tycoon. The game offers a variety of gameplay modes, each with different restrictions (except for Freeform). A Freeform game in Zoo Tycoon 2 allows you to create the zoo of your choice, with the only limitations being space, animals, and objects. The player's money supply is unlimited, and all items are available from the start of the game, except for those that can only be unlocked in scenario and challenge games.
