As a perk through the Point shop, you can acquire a dead man trigger. Basically if you die and you have a C4 in your inventory the C4 is detonated (but with reduced range of course). I thought it would be an interesting concept to have but balance is the obvious issue here. Should the radius be , medium, or really small? Should it do enough damage to instantly kill a player or just wound them? My thinking is it would finish off wounded players but higher health players would still be able to survive. Since this is a game changer I would suggest somewhere around 75- 100K points for it, but it probably could be better priced.
The main issue with this is that you can't warn for it like you could a jihad. Any traitor buddy that is near you could potentially be damaged or harmed without warning; meaning you would be slain. Use a jihad. -1
If you desire the same effect, just have a frag if you're about to die and cook it as they shoot you. If you're lucky they won't notice it.
