1) You can kill all the drones by your hands, but can’t tell about it to the cau, and forced to put gas, even if all drones are dead, I think it can be quiet funny to go there kill drones and ask Capitan why does we need mutagen anyway, or some invictus dialogue option, that you kill by your hands, not with a gas. There is a dialogue for a lesser option and I think it will be a fun option to solve quest with a more intense fight.
2) Been able to tell the drone that you destroy Fort Apoge. They may not believe you and maybe no reward or exp needed just tell that you beat all the fort will be dope.
3) I’m sure that this one won’t be added, but been able to attack cau near the base of drones and not initially agro all the protectorate, or at least have some explanation why all of the cans are suddenly not happy to see you. I mean near the drone base there not only you who can kill them. Not without any consciences but have some way (persuasion check to commander, who are too not happy to see them and kill the drones) to kill cau and stay in protectorate will be nice.
4) After you join protectorate and have your house maybe there may be some free drone ambush, if you don’t get the security, now it’s only good for one event, but the ambush in a house was fun for the first part.
