I think it could also be a good idea to be able to find some sort of passive item that enhances drones. I'm not thinking of anything that would increase their effects, since I actually think that the general impact they have is perfectly fine. Rather, I'm thinking of items that cause one of the following: -absorb some of the damage they take -increase their health regeneration -tone down the increase in repair costs (this one sounds like the least likely option to me) -allow drones to collect health pickups when you don't need them yourself. How these items work in combination with yourself can probably be done in different ways. I don't know if the game can register if an enemy dies because of a drone or the player it's with, so that might also change the possibilities to implement them.
