The B2 super battle droid, also known as the super battle droid or SBD, was the upgrade of the B1 battle droid, it was also created by the Techno Union. It was taller and stronger than the original B1 and had a wrist-mounted blaster. In addition to these obvious physical improvements, the super battle droid could function completely on its own, without the need of a control ship to fight.

Star Wars gamesEdit
Star Wars Battlefront: Renegade SquadronEdit
In Star Wars Battlefront: Renegade Squadron the super battle droid still has various built in weapons such as the wrist blaster in place of the blaster rifle when it is chosen from the customization menu, however they can now carry non-built in weapons such as the chaingun, in stead of their built in weapon. The non-built in weapons do not have a disadvantage in comparison to built in weapons, during the game, as Jedi and other units cannot remove other units weaponary in Renegade Squadron.
Star Wars: Republic CommandoEdit
In Star Wars: Republic Commando, the B2 appears as a much-enhanced battle droid. It is much harder to dispose of than the original B1, taking several shots with a DC-17m sniper attachment, one shot with the anti-armor attachment, or scores of shots with the blaster attachment. The B2 has a powered-up blaster cannon on its arm along with wrist rockets. It is one of the hardest of all of the enemies in the game. Melee attacks, however are the most effecient way to kill these droids, but watch out they will hit back. Generally five melee punches with your vibrobladed gauntlet will kill them.
In Star Wars: The Clone Wars the super battle droid does not pose much of a threat in most situations, however they are fairly difficult to defeat when the player is not in a vehicle. For this reason, they are rarely seen in levels that are vehicles-only.
LEGO Star Wars seriesEdit
In LEGO Star Wars: The Video Game and LEGO Star Wars: The Complete Saga, the super battle droid appears on many levels, often accompanied by B1 battle droids. If you buy the 'use old save' extra, you can have it on LEGO Star Wars II: The Original Trilogy (only if you bought it on the first one).
