Review by Ron Neufeld, 92%. "This add-on is more than just new levels; it's an excellent game in itself."

Review by Robert Mayer, 3/5. "Gamers addicted to lightsabers and force powers will love it; those more in tune with blasters will be less thrilled."

Review by Timothy Krupinski, 92%. "It has everything a good companion disk should, adding new features such as colored lighting and new characters, while staying true to the formula that made Jedi Knight such a success."

Review by Emil Pagliarulo, 5/5. "The mother of all add-ons, Mysteries of the Sith is a monumental achievement not only in expansion packs, but in narrative 3D games as a whole."
