Refplace: GURPS Monsters, NPCs and things that make life interesting!

The GURPS Basic Set includes a number of animals and monsters but you can never have enough!

Because GURPS covers so many genres and settings it cant include everything in one book, nor frankly would it be wise to. If you want to play fantasy why buy a book filled with aliens, modern spies, and super villains? Most setting and genre books will also include some potential adversaries and those are not included below.

Fourth Edition

Aliens: Sparrials Think alien monkeys with no sense of property rights.

Creatures of the Night A series of 5 books with monsters suitable for the horror genre. Some can be used in a fantasy or other setting, but beware many are very scary and dangerous

Dungeon Fantasy Monsters A series dedicated to supporting the Dungeon Fantasy line. 5 books.

Template Tool Kit 2:
Dungeon Fantasy Roleplaying Game Boxed set that includes a monster book. Also a digital version so it will never go out of print.

Nordlondr Ovinaboken is a great full color bestiary for the Nordlondr setting. Its Viking themed but has a lot of generic monsters and things that can be used in other fantasy settings.

Also by that publisher Garden of Evil; The Bugstiary; Serpents of Legend
