Star Wars Galaxies: Rage of the Wookiees was the second expansion pack to the MMO Star Wars Galaxies. It was announced on March 9, 2005 and released on May 5, 2005. This expansion pack added the Wookiee planet of Kashyyyk and its corresponding space sector. Kashyyyk is different from the previous ten planets: rather than being 16 square kilometers of openly navigable area, it is divided into a small central area with several instanced "dungeon" areas. A new space zone was also added. Other content added in this expansion included the ability to add cybernetic limbs to a player character, quests for three new creature mounts and two new starships. A substantial portion of the content for this expansion was adapted from the film Star Wars: Episode III Revenge of the Sith which was released to theaters at approximately the same time as the expansion release. Customers who purchased the expansion also received a limited-edition Varactyl player mount from the digital download or a BARC speeder if they purchased the box set.
