In Game Description
"Pac-Asites are a strange combination of a velociraptor and a pit-bull. They have the pack hunting instincts of velociraptors, with the size and ferocity of a pit-bull. Watch out for the fiery Pac-Asite deep in the lava tubes!"
Pac-Asites are constantly charging towards Pac-People. Pac-Asites are a danger to other species and races as well.
