From publisher blurb: Enemies of Epic Proportions! One of the most exciting aspects of the Starfinder Roleplaying Game is the ability to fly your own starship. The game not only has a whole new set of rules for combat in starships, but the Starfinder Alien Archive even features a handful of monsters that have two sets of statistics entries: allowing them to be fought as either a standard monster, or as a sort of ersatz starship. As cool as dogfighting in starships is, using one to fight a ship-sized monster is even cooler, and the selection of starship monsters in the Alien Archive just didn’t seem like enough, so this book presents four titanic new monsters, each of which can be fought either on the ground or with a starship: the astral kraken, the living asteroid, the space crystal, and the space hydra.
