Space is filled with extraterrestrial species that are both benign and malevolent. Starfinder: Alien Archive 2 contains a collection of new creatures designed for the Starfinder role-playing game! From laser-firing Tashtari and starship-devouring stellar protozoa to dust rays and skeletal undead soldiers – the beings in this collection will challenge adventurers throughout the galaxy. Additionally, many of these species are not just intended as foes to confront – they come with rules that allow players to create characters from them! In this book, you will find: - Over 100 bizarre life forms, both classic and new, from ravenous Akatas and silicon-based Quorlus to radioactive Pluprex demons and parasites that inhabit the void. - More than a dozen ethnicities with complete player rules, allowing you to play everything from enhanced bears to sentient snails. - New alien technologies that give your characters an edge: armours, weapons, magical items, and spells. - New rules for magical polymorphism, environment-based archetype transplants to quickly adapt creatures to any world, and much more!.
