I did this for over three hours yesterday, there has to be more to it.
Not sure what I'm doing wrong. Is there a certain order things need to be done in?
You only need to activate two of the turrets up top to get the droid to take damage here. The two panels below are not required but they do help with the fight. Not sure why the droid resets though.
The droid becomes immune to damage at 3 health intervals so you will need to activate the two turret up top three times for the entire fight.
