Score x2 is an extra in all of the Lego Star Wars games. When turned on, all stud values are multiplied by 2. For example, silver studs are worth 20, gold studs are worth 200, blue studs are worth 2000, and purple studs are worth 20000. When combined with Score x4, Score x6, Score x8, and Score x10, all stud values will be multiplied by 3840.
