The B3 ultra battle droid was a powerful prototype battle droid designed by the Confederacy of Independent Systems and deployed approximately five months after the Battle of Geonosis. The B3 ultra battle droid was based on the B2 super battle droid model, though it was far larger and bulkier than the B2. The B3 had two large arms fitted with a flamethrower and a wide-spray plasma cannon. Two smaller arms, located underneath the primary limbs, featured deadly rapid-fire blasters, similar to the B2 battle droid. In addition, the ultra droid had a magazine of brilliant missiles located to the left of its large, neckless head. The B3 also had a density projector to increase its weight, keeping it from falling over in combat. It is was used by the Axis of Empires. The B3 suffered from many production problems and never really excelled in combat and was replaced by the B4 ultra Battle droid which it is now named instead of the B3 ultra battle droid..
Performance[]
While a stronger and more heavily armed B2 Super battle droid, initial B3's suffered mainly from mobility and were easy to push over, in fact BJ Blazkowich demonstrated this weakness pretty well to the Axis of empires. Because of production costs the B3 rarely saw combat until the Combine of empires modified the armour of the B3. While more powerful than the B2 super battle droid, combat performance was mediocre with the B3 being revised. The newer B4 had stronger armour and less weight than the B3 allowing it to mount the weapons that the B3 should have been capable of using.
