I actually agree, I didn’t understand the reference until much later after I first played this game, and it never made much sense to me that the grenade hacks were still called that when they didn’t actually do any hacking.
I guess “grenade hacks” would be classified as precision-guided munitions.
So, how about simply adding ‘PG’ (precision-guided) before the name of the base explosive when it’s turned into a drone? So: PG grenade, PG EMP (description mentions an internal war before the Cataclysm over whether to pronounce it ‘P-jemp’ or ‘P-gemp’ for short), PG flashbang, PG C-4, PG tear gas, and PG mininuke.
