The lightsabers of Maulkiller consisted of two lightsabers that belonged to Maulkiller, who was a Dark Side Adept. Maulkiller utilized these lightsabers for purposes of killing and widespread devastation.
Acquiring these particular lightsabers was exclusively tied to obtaining the bonus preorder avatar from GameStop, specifically for those who preordered the video game Star Wars: The Force Unleashed II on either Xbox 360 or PlayStation 3. When wielding these lightsabers, players experienced a reduction in their available Force energy when drawing upon the Force. The preorder bonus information referred to it as "Maulkiller Silver Saber Crystals".
