The Separatist Alliance’s B1 Battle Droids are manufactured to attack in massive numbers and wear down enemy forces through raw attrition alone. But that does not mean they don't have other purposes to serve as the Separatists seek to overthrow the Galactic Republic. Other series of battle droids perform a variety of tasks for the Separatist military and a select few droids are outfitted with different weapons that give them unique capabilities.
The B1 Battle Droids Upgrade Expansion contains four unpainted, finely sculpted B1 Battle Droids different from those found in the Clone Wars Core Set or the B1 Battle Droids Unit Expansion. These miniatures arrive on frames, giving you freedom to customize their appearance. On the battlefield, these miniatures can become the basis for a new unit of B1 Battle Droids, or you can use the new heavy weapon and personnel upgrade cards options they bring to enhance your existing units.

• Upgrade your B1 Battle Droids' personnel! An OOM-Series Battle Droid miniature and a B1 Security Droid add even more tactical options to your units.
• Bring more firepower to the battlefield with an E-5s B1 Trooper or a Radiation Cannon B1 Trooper.
