As a full-fledged expansion of the Star Wars Jedi Knight: Dark Forces 2 changes several things, one of which is ignoring the ending of the dark side. As a direct story continuation, Star Wars Jedi Knight: Mysteries of the Sith picks the story from the light ending, and players meet the protagonist of the previous game, Kyle Katarn, in the role of the Jedi Master training Mara Jade. After the introduction, where Katarn defends the New Republic outpost from the imperial troops, players will control the apprentice, Jade, on her mission to find a Sith temple.
SWJK: Mysteries of the Sith is a first-person shooter with a possibility to switch to the third person view. Unlike the original game, players don’t have the moral choice system, because the single-player story has a single positive route. The game has 14 levels as a story campaigns as well as 15 maps for multiplayer battles. As a Jedi apprentice, Jade will have not only to the ranged weapons, like blasters but lightsabers and force powers. But in multiplayer, that supports up to eight players to fight as the characters from the Star Wars films.
