STAR WARS™ Jedi Knight - Mysteries of the Sith™

Star Wars Jedi Knight: Mysteries of the Sith is an expansion pack for the 1997 first-person shooter Star Wars Jedi Knight: Dark Forces II, developed and published by LucasArts for Microsoft Windows in 1998. It was re-released on Steam in September 2009. The expansion includes a new single-player story mode and fifteen multiplayer maps. The single-player story, set in the Star Wars expanded universe five years after the events of Dark Forces II, follows both returning protagonist Kyle Katarn, a Jedi Master and mercenary working for the New Republic, and Mara Jade, a character featured in numerous Star Wars expanded universe works, who is being trained by Katarn in the Jedi arts. After Katarn goes missing while investigating an ancient Sith temple, Jade continues her studies on her own while undertaking missions from the New Republic, eventually leaving to find Katarn. Mysteries of the Sith uses the same game engine as Dark Forces II, the Sith engine, but features several technical improvements, including colored lighting, new textures and models, and better AI. The expansion puts more emphasis on lightsaber combat and Force powers, introduced in Dark Forces II. The multiplayer mode allows up to eight players to play online or over a local area network. Upon release, the expansion received generally positive reviews. Critics praised its story and AI improvements, but felt there was room for additional improvements and criticized its inconsistent difficulty and certain gameplay elements. It was followed by Star Wars Jedi Knight II: Jedi Outcast in 2002, the next main installment in the Jedi Knight series. A reverse engineered source port called OpenJKDF2 supports Mysteries of the Sith.
