The Pacific Rim sourcebook is a sourcebook for Cyberpunk 2020 detailing the countries, people and corporations of the far east.
The book is written in-universe in a similar style to a travel guide and gives information on the various east Asian countries such as Japan, China, Unified Korea, the Philippines and even Australasia.
Several smaller Asian countries are included such as Myanmar, Laos, Singapore and Brunei as well as New Zealand and Hawaii.
Several new roles have been created, such as the Pirate, Private Investigator, spy and Runners. Classes like the Solo have alternate roles, such as the Shinobi and Tatsujin, who focus more on martial arts than guns.
