Smart thinking. X12 is very handy for computer-based activities. He renders your searches untraceable.
You research your enemy and get some general information about the droids that you are going up against here. Whereas battle droids are generally quite flimsy and must be equipped with blaster rifles, these Mark II battle droids are bulkier and have blasters built into their arms. They are no more independent, though; both models rely on a signal to command them. If the signal is cut, they shut down.
As far as gameplay rules are concerned:
Battle droids are Mooks with Guns pools of 5 dice.
Super battle droids are Mooks with Guns pools of 6 dice and an Armor rating of 1.
Mooks are generally easy targets, meant to be lined up and knocked down by the pluck protagonists- in this case, that would be you! Mooks require three successes to kill, and that is raised by one for every point of Armor a mook has.
However, Lightsabers make short work of them! They have a base damage of 6*, meaning they have a Mook Killing Power, meaing you only need to two successes to kill a Mook. They also ignore Armor, meaning that you only need two successes (rather than four) to kill a Mark II.
Does that all make sense?
