Specialization Classes in Mass Effect are specializations of a class. Players can opt for different branching paths and continue to benefit from the features of the initial class, while also gaining unique abilities for their Subclass. Specialized class talents are unlocked once assignment UNC: Rogue VI on Luna has been completed.
There are six specializations, two of which are available based on your initial class choice. Selecting a specialization offers access to a new trait that add ranks 7-12 to your class specific talent; ranks 1-6 are unchanged, and grant the same bonus when you take ranks 7-12. You can only unlock once per character and will then carry over to subsequent playthroughs with that character.
