In Bios: Megafauna, a reworking of Phil Eklund's own American Megafauna, players start as proto-dinosaurs or proto-mammals, starting in the post-holocaust world of the Permian catastrophe. Animals are tracked by dentition, size, aggressiveness, swiftness, browsing, grazing, burrowing, swimming, behavior, and insect-eating. Plants and animals that have gone extinct are collected in an area on the map called the tarpits. These tiles are distributed among the most populous players as victory points during four scoring rounds.
Players cope with intense competition and environmental changes by starting new species and mutating them. Create bizarre chimeras, from vegetarian velociraptors to flying dolphins. Establish subterranean civilizations, tame fire, or just be super-sexy.
This variant allows you to start at the beginning of the Paleozoic era instead of the Mesozoic era. Features a player placard which allows you to track adaptations such as eyes and dentition with the aim of becoming a tetrapod by the end of this era.
This includes a separate player mat for this in PNG format.
These are the English living rules to Bios Megafauna in multiple pdf files. They are formatted just as the rules that come in the box with living rule changes in red.
This version contains all living rules through September 28, 2012.
