Here's why:
* Kyber Crystals: In the Star Wars universe, lightsaber crystals are called kyber crystals. They come in various colors, each corresponding to a different alignment in the Force. While some crystals are naturally colored, most are imbued with their color through the Force user's connection to the Force.
* No Specific Black Crystal: The Force Unleashed doesn't feature a specific black kyber crystal. There are other, more common, colors that are often associated with the dark side (like red), but not black.
Possible Misunderstanding:
It's possible you're thinking of the game's overall design or a specific visual element within the game.
* Dark Side Alignment: The game heavily leans into the dark side of the Force, and the visual aesthetic reflects that. You might be associating this with a "black color crystal" due to the prevalence of dark colors in the game.
* Starkiller's Lightsaber: Starkiller, the main character, wields a double-bladed lightsaber. While it has a dark and intimidating appearance, the color of its crystal is never specified.
