Multiplayer
Mysteries of the Sith includes fifteen multiplayer maps, four of which only allow players to battle with lightsabers. The player can choose an avatar and the lightsaber color, and compete with up to seven other players over the internet or a local area network. The game includes a ranking system that tracks the player's experience. Multiplayer mode allows the use of pre-set characters featured in both Mysteries of the Sith and Dark Forces II. There is also a choice of characters from the Star Wars films, such as Luke Skywalker, Darth Vader and Boba Fett, who was already a playable character in the Dark Forces II series. Each type of character has advantages and disadvantages.
Several locations from the Star Wars films have been recreated as maps for multiplayer gaming. These include Luke's home on Tatooine from A New Hope, the carbon-freezing chamber on Bespin from The Empire Strikes Back and the Emperor's throne room on the Death Star from Return of the Jedi. The capture the flag multiplayer mode has been altered since Dark Forces II. The player must now steal a ysalamir from the other team and return it to his or her own base. The ysalamir has the added effect of reducing the Force powers of the player who is carrying it.
Plot
Mysteries of the Sith is set in 10 ABY, six years after the events of Return of the Jedi and five years after the events of Star Wars Jedi Knight: Dark Forces II, continuing from the "light side" ending. Kyle Katarn (voiced by Rino Romano) is now a Jedi Master and has taken on Mara Jade (Heidi Shannon) as his apprentice. Like Katarn, Jade is a former member of the Galactic Empire, but joined the New Republic to become a Jedi Knight.
The game begins in a New Republic outpost on the planet Altyr Five where Katarn is training Jade when Imperial forces launch a sneak attack on the base. The player takes control of Katarn to defend the base from the stormtroopers and get to the command center. Once there, it is revealed that an evacuation cannot take place because of bombardment by two weapon platforms disguised as asteroids. Katarn leaves Jade behind as he travels to the asteroids to destroy them.
After this section of the game, the player takes control of Jade. Katarn reveals that he has discovered information as to the whereabouts of a Sith temple on Dromund Kaas. He leaves for the temple, and in the meantime, Jade must take on new assignments for the Republic and continue her studies of the Force.
Jade completes her missions for the Republic but hears that contact with Katarn has been lost. She heads to Dromund Kaas to try to find out what has happened to him. At the temple, she discovers that Katarn has been corrupted by the power of the dark side located within the temple. Failing to convince him to turn back, Jade battles him in a lightsaber duel which finally turns him away from the dark path, as she disengages her lightsaber and he finds he cannot go through with killing her.
Reception
In the United States, Mysteries of the Sith debuted at #10 on PC Data's monthly computer game sales chart for February 1998. It fell to position 15 the following month, with an average retail price of $28, and was absent from April's top 20. The game was well received by critics. It holds an aggregate score of 75.60% on GameRankings, based on five reviews. Mysteries of the Sith has been described as a good quality expansion pack and a "worthy addition" to the world of Jedi Knight, but with room for improvement in some areas.
Next Generation reviewed the PC version of the game, rating it four stars out of five, and stated that "on the whole, MOTS gives notice to expansion pack designers everywhere: It is possible to create an exceptional gaming experience within the creative possibilities of an add-on. The foundation has already been laid."
The gameplay of the single-player mode received mixed reactions. Paul Mallinson of PC Zone stated that "Mysteries Of The Sith starts off brilliantly and gets better and better and better the further you get into it. The progressive nature of the constantly evolving storyline sees to that." In contrast, Michael E. Ryan of GameSpot stated that the game is uneven and the challenging levels are only at the end. This adversely affects the gameplay by creating a steep change in how the game must be played. General aspects of the gameplay were seen as improvements, such as the artificial intelligence.
The multiplayer side of Mysteries of the Sith was received positively, but did not completely escape criticism. Emil Pagliarulo of The Adrenaline Vault questioned why certain features seemed to be missing from the multiplayer mode that were present in the single-player mode. One such feature is the rancor which appears prominently in a single-player level but is not in any multiplayer maps.
The development of the graphics in Mysteries of the Sith was seen as an improvement with particular praise for the new colored lighting effects. However, not all new graphical developments were well received and some reviews highlighted that smoke effects from the carbonite weapon are particularly poor. Ryan criticized the whole graphical implementation of the weapon: "The Carbonite gun was a long awaited weapon, but the effects and the resulting graphic for frozen foes are really quite bad."
Mysteries of the Sith received praise for its use of sound. Heidi Shannon was described as an "excellent choice" for the voice of Mara Jade. The musical soundtrack by John Williams received specific commendation for its quality. Pagliarulo stated that its use is executed very well within the game: "Mysteries of the Sith manages to use the right piece of music at just the right moment."
