When you place explosives in a persons pocket they blow up, but does this work with c4 or do you still have to use a detonator?
(i would test but im out of c4 and cant find any replacements...)

were do u get a detinator?

You can find them with c4 sometimes, i once found one lieing in a box in an abandoned house so look around or just check the wiki.

When you put C-4 in their pocket it will become armed and wait for you to trigger it.

haha that is awesome...does that mean you could assasinate someone from miles away or will it despawn if you leave the general area like mines do?

I'm not sure of the range of it, but you can definitely get Hidden and set it off without anyone getting suspicious.

ahhh, if only i had known this when trying to assasinate a woman for a quest...i had to run out of there after firing my follower so my good character didnt lose standing due to the deaths of guards and bystanders...

Interesting fact that would have diffently helped a long time ago if I knew it at the time. Oh well I got the job done the old fashion way....
