Ball mode was the mode droidekas would go into to quickly move around the battlefield. When in this mode a player can do the equivalent of jumping if needed. The only drawback of this mode is it leaves the droideka shieldless which makes it easy (as easily as a unit without a weapon) to destroy while moving, or by just sitting in one place before you have a chance to shoot back. Ball mode is a mode also in which the unit could not shoot back or deploy its shield, therefore making it vulnerable to attack, while making the droideka able to move faster. Droidekas could deploy from this mode, but it took a little time to do this and deploy its shield as well.
