Now I want to get a 20 kill streak beating everything to death with a chocolate bar.
All my food shall have a kill before I eat it!
Instead of marking it there you could do what dwarf fortress did and have kills listed in the item’s description. It would leave no possible confusion about ammo. And then it could list 5 zombies, 8 rabbits, 12 zombie dogs… or whatever you kill with it.
Maybe also say if you got it off a dead npc/player.
Ex: Double barrel shotgun
I pried it from John Smith’s cold dead hands.
Kills:
5 zombies
8 rabbits
12 zombie dogs
1 zombie hulk
1 Nicolus Cage
