This document describes the rules for a board game called "Species" where players take control of one of four alien species with different abilities. The goal is to gather resources, develop new abilities for attacking, defending, and movement, and wipe out the other species while spreading across the game board. Players take turns acquiring resources, generating new members of their species, moving members across hexagonal spaces, and attacking adjacent members of other species through dice rolls modified by any bonus abilities. The winner is the last species remaining on the board.
