Animals Lack Attributes: Animals in ZT2 squat to poop, but nearly all have no orifice to poop through (the hippos do have an anal dot for whatever reason).Also in the second game, both male and female okapis have horns.Just like with the previous titles, the sequel and its expansions were mixed into one big Updated Re Release named Zoo Tycoon 2: Ultimate Collection. This game also had expansion packs: Endangered Species (2005), African Adventure (2006), Marine Mania (2006), and Extinct Animals (2007). The sequel, Zoo Tycoon 2 (2004), brought the franchise into the world of 3D graphics and changed several mechanics, while still following the same set of ideas. The three original games would later be combined in Zoo Tycoon: Complete Collection, a compilation which also came with new bonus animals, objects and an additional pack of endangered species. It was followed by a couple of expansion packs which added dinosaurs and other prehistoric animals ( Dinosaur Digs, 2002) as well as marine life ( Marine Mania, 2002) to the mix. The first game was released in 2001, to fairly positive reviews. Zoo Tycoon is a series of video games (mostly for PC) where the player is given the task of managing a zoo, keeping both its guests and animals happy and healthy, or not.
