Modules require the base game of Nature to be played. 

Discover the mysteries of the rainforest, where surprises are concealed behind every leaf in the canopy. 

Amazon Rainforest introduces brand-new traits and mechanics into the Nature ecosystem. Defend against predators with deadly Poisonous skin, use Powerful Jaws to take down larger prey, or evolve Climbing to access fruit high in the trees. 

Amazon Rainforest is a location module that changes the setting of Nature.  Add or combine modules with Nature to enjoy more ecosystems and endless replayability.
