@gilga - just had a thought.
Now that we are in a dungeon crawl, what if instead of having the drones right with us and shooting at whatever we shoot, what if we had them secure each intersection we leave behind us?
That way, the ghouls can never overwhelm us from front and rear. Also, right now they are so noisy we have no chance of stealth.
But if they were some distance from us, their noise would actually make it easier for us biologicals to be sneaky, masking our sounds.
Once we pass each subsequent intersection, they could jump up to the one we just passed.
Of course, something like this might require you staying on site and directly piloting them, and also you'd have to be piloting them to control who they shoot, since there may be friendlies running around down here.
Just some thoughts …your call!
