Fera Vita

This science-fiction roleplaying supplement expands planetary exploration with alien wildlife, survival hazards, and environments ranging from towering forests and swamps to oceans, deserts, and icy tundra. It includes more than fifty strange creatures, some suitable for interaction and others posing serious threats. An animal-generation system allows Game Masters and players to create new species for their own worlds. Expanded rules cover poisons, fatigue and exhaustion, flight, swimming, underwater adventures, and the equipment needed to survive on alien planets.
