C-4 Plastic Explosive

C-4 plastic explosive is a weapon in Fallout: New Vegas.

Characteristics
Also known as Demolition Composition 4, C-4 plastic explosive packs quite a punch. Being the standard-issue demolitions charge for the army before the war, it's still finding much use in the harsh environment of the Mojave Wasteland. A remotely detonated charge, it can be implemented in many ways for effect and entertainment. Like most explosives, it can be reverse pickpocketed. The Detonator is acquired separately. Unlike hand-held explosives like the Frag Grenade or Dynamite, C-4 causes a huge explosion and is not to be detonated in close range of the explosive. It is possible to set up an ambush with C-4.

Reverse pickpocketing plastic explosives will arm it. If you detonate while hidden and stay hidden, you will not be blamed for the crime. In fact, reverse-pickpocketing isn't necessary, if your target(s) stands in one place or revisits a spot regularly. You can drop a C-4 charge in plain view of anyone. As long as you detonate it while hidden, you will not suffer any ill reputation effects. However, if you hit your victim when throwing down the charge or if you fail to kill your target with this initial blast, they will be hostile to the player.

If you drop multiple C-4 charges, they will all go off when activating the Detonator.

There is a bug in which whenever you try to either select C-4 from your hot keys OR from your Pip-Boy, your game will immediately freeze. (Running patch v 1.02)
