From WWF Russia:
'Rescue the Russian Leopard' is an ecological strategy game, although it also incorporates elements of other games such as photoshooting. This game is modelled after a real-life situation. Ahead lies not escaping virtual monsters, but dealing with real-life problems. Your goal is to significantly increase the endangered Far Eastern leopard population from 30 to at least 100 animals, or ensure that several leopard families live in the Ussurian Range reserve. You will have 30 years of game time in which to achieve either of these objectives. The best player's strategies are able to be implemented by WWF for its real conservation activities. The game is suitable for all ages.
