Little is known about the origin of Amplification crystals. Two of these silver crystals were used by Maulkiller, an experiment of Darth Vader who was created by using genetic data from Galen Marek and Darth Maul. Maulkiller eventually died due to physical and mental instabilities, and the fate of his crystals was unknown.
Behind the scenesEdit
In Star Wars: The Force Unleashed II, these crystals can only be unlocked using a Gamestop pre-order code. The crystals provide extra damage from all attacks.
