An undeniably superb sequel to Dark Forces.
Dark Forces II: Jedi Knight is set several years after Return of the Jedi, and before the New Republic is finished establishing itself. With the death of Palpatine one of his followers, Jerec, and his six loyal Dark Jedi turn their attention to finding the Valley of the Jedi so they can restore the Empire as its new rulers. After prying some vital information from one of the last Jedi of the Old Republic Jerec sets out to find the Valley. Standing between Jerec and the Valley, however; is Kyle Katarn, a force sensitive son of a man that Jerec murdered. The plot is rather simplistic like the one found in Dark Forces, but it still manages to be entertaining.
In JK the gameplay is a lot like most first person shooters with one exception. You get a lightsaber, and can learn and use Force Powers. While mowing down Bounty Hunters and Stormtroopers with your large assortment of weapons, you can choke your enemies, or even protect yourself from projectile weaponry. The system works quite well, but more often or less the Force Powers are unnecessary unless you need to reach a high place with Force Jump. The game could have worked fine without them.
The graphics are outdated obviously, but even for their time they were... interesting. The characters are all extremely blocky, and Kyle seemed to shave after every FMV sequence which made little sense in terms of continuity, and some of the textures (particularly grass and sand) are quite bizarre. Still the levels are large and have excellent architecture.
The sound is okay. The voice acting is decent, and the sound effects are mostly from the Star Wars sound library. The entire game uses the classic John Williams score that is in CD audio format on both of the JK discs, so the music isn't interactive and doesn't really pick up when you enter battle like in Dark Forces and JK's sequels.
Dark Forces II: Jedi Knight is the best in the JK saga and second best in the Dark Forces series as a whole. If you liked Jedi Outcast and\or Jedi Academy then you owe it to yourself to play Jedi Knight. It's long, has impressive level design, and like Dark Forces an impressive amount of atmosphere.
