Chronic Logic has announced Wildlife Tycoon: Venture Africa for Mac and Windows is available now for download.

The game is set in the African Serengeti. Players must build the natural ecosystem by purchasing and breeding animals and ensuring sufficient food and water are available for each creature.

Animals include herbivores, such as zebras and wildebeests, along with ultimate carnivores, like alligators and lions. There's obvious risks: if your animal population grows too carniverous, they'll eat other animals. And some animals, such as elephants, will dominate food supplies.

Successful breeding strategies are rewarded with jewels, which can be exchanged for new watering holes and food supplies to further expand their ecosystem.

A demo of the game is available for download. It costs $19.95.
