I need to complete a mission using only hands or feets (as someone called them) and using my high heels didn't work, so I put my stupid head on (also available in shops - see Navin for details) and asked here.
Next week, I will be asking why I can't eat an apple with my ear.
I've discovered another thing though. When you go to fight someone, and have a look at their weapons, they might have fancy schmancy guns, but there's No Ammo in them.
Ptchew, ptchew with my little Mag 7 (or whatever it is) and they're dust. Don't try it on me though. I'm nice.
That's because they're inactive. The missions system added them to the missions, requiring those doing the missions to attack/leave/mug/hospitalise them. Because they were attacked, they used up all their primary and secondary weapon's ammo. That's why they have guns, but no ammo.
