Aliens has the complete rules for building aliens for GURPS. They are almost exactly the same rules as found in GURPS Fantasy Folk and Compendium I. They are an excellent well-balanced set of rules¸ but they are GURPS-centric and are unlikely to be useful for other games. To supplement this¸ they include over two dozen aliens built with these rules and fully fleshed out. Interesting playable races include the Cidi¸ tiny cute creatures that spend a lot of time using or complaining about being treated 'cute' and the Jaril¸ giant engineers who are rebuilding their race. They also offer something of a universe to play them in.
