This is a unit / operative extension pack (in French) that introduces the elite clone-trooper squad known as the Bad Batch (also called Clone Force 99) into the Galactic Republic (or as a mercenary unit for the Rebel Alliance) in Star Wars : Legion.
It expands your army roster and gives you new tactical options, rather than acting as a standalone game. A core game (base set) of Star Wars : Legion is required to use this expansion.
