Outer space is full of alien species both benign and malevolent. Starfinder Alien Archive 2 presents a host of new creatures designed for use with the Starfinder Roleplaying Game! From the laser-breathing tashtaris and starship-eating stellar protozoans to dust mantas and undead bone troopers, the creatures in this codex will challenge adventurers no matter where in the galaxy they may travel. What's more, player rules for a variety of species let players not just fight aliens, but be them!

Inside this book, you'll find the following:

• Over 100 bizarre life-forms both classic and new, from the voracious akatas and silicon-based quorlus to radioactive pluprex demons and void-dwelling vermin.
• More than a dozen species with full player rules, letting you play everything from an uplifted bear to a sentient slug.
• New alien technology to help give your character an edge, including armor, weapons, magic items, and spells.
• New rules for magical polymorphing, environmental template grafts to modify creatures to fit any world on the fly, and more!
