Ngl, this game heavily fleshes out the hierarchy and personality of droids more than the movies and even the Clone Wars tv show did to an extent.
B1s, same old, I love them B2s, are more competent, and probably the most neutral in terms of personality. They follow orders and simply state whatever it is they're doing. Blunt and direct. Most of the time, with a slight hint of boasting against B1s. BXs, are aggressive and borderline tactical. They often take the lead role but they also seem to be the most arrogant and bloodthirsty. They are condescending around most droids not of the BX model, and downright hateful to the B1s. I could definitely get used to seeing them more like this.
If you wait for the droid at 4:38 to finish talking about his promotion and it being a dilemma, then kill him afterwards, Cal will say “Dilemma solved.”
B1 droid: "OKAY!!! SWITCHING TO STEALTH MODE!!!"
