Taking place after the events of the original Dark Forces, players once again assume the role of Rebel operative Kyle Katarn, who destroyed the Arc Hammer, a gigantic dark trooper factory, in the first game. This time, Katarn's investigating his father's death, but Kyle realizes that he is sensitive to the Force.

His mission takes players to a dozen planets as he uncovers a Sith plot to harness the Valley of the Jedi. I don't want to ruin anything for new players, but the story is pure
Star Wars, much like
Knights of the Old Republic, which came out in 2003, six years later. Throughout the game, Kyle unlocks additional Force powers, becoming a powerful Jedi in his own right.
He's on a race against the Sith to stop them from unlocking a terrible power, but he's largely on his own. There's Jan Ors, his faithful companion from the first game, but she's always working behind the scenes to provide support to Katarn.
It does feel like Star Wars, but the atmosphere is grittier (partly due to the bleak art design), and the worlds Katarn visits always feel a little lifeless. There are stormtroopers, Sith, and other enemies to burn down with your lightsaber, but they're empty. It's a problem common to many older games. They don't have shops, stores, and homes. They're just endless corridors and control rooms which open up doors.
Thankfully, you're too busy slicing your way through hordes of stormtroopers that you rarely take a moment to look around. The atmosphere might be lacking compared to contemporary games, but it doesn't feel like a significant problem.
