Chryssalids are four-legged, fast-moving, insectoid creatures. Usually encountered in small swarms, they have a devastatingly powerful claw attack. They use the corpses of other creatures as egg incubators, with the eggs hatching extremely quickly, and the hatchlings being almost as powerful as adults from the moment they are born.
