So, my players, being the clever, non-linear thinkers that they are, did something very clever to deal with an infestation of exsurgent jellies. They loaded capsule rounds with a PH 13 alkaline and shot the acid-filled exsurgents with them. Given that the jellies have a very low PH biology--their secretions are acidic, and they can spit acid as an attack--simple chemistry means we have a violent and highly exothermic reaction...
I ended up ruling that each capsule round would lodge in the main "bubbles" for one round (on the logic that, normally, bullets just pass right through and do minimum damage to the jelly) and dissolve, allow the alkaline to react directly and deeply within the jelly, doing considerable damage to the creature--I rolled 2d10+5 per capsule, and, thanks to the PCs having loaded up their drones' assault rifles, some of the jellies had 5-10 capsules in them by the second round of combat. It was... impressive.
So, three points.
Point the first, for an off-the-cuff "you're doing what?" GM rules call, opinions? Does this sound about right?
Point the second, has anyone else had PCs come up with highly unusual weapon payloads, and is willing to share stories of excellent successes (or hilarious failures)?
Point the third, my PCs are starting to feel that the Gunnery skill is overpowered, because the tactic they've been doing is having the drone AIs go on Full Defense, and have the PCs use gunnery to fire the drone's weaponry systems remotely, using a gyromount to keep the weapon stable during the evasive maneuvers of the drone. Is that generally accurate, or is there something I've been overlooking that brings gunnery back into balance? Yes, I know that you need a mounted or emplaced weapon to use Gunnery, but I've got a combat engineer with a CM and blueprints; I can't really take away his toys without being very obvious that I'm trying to do that, and, besides, that feels rather dishonest as a tactic and doesn't actually solve the problem.
