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, C4 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 C4. Assuming your enemy will still be alive when the C-4 explodes. Reverse pickpocketing plastic explosives into someone's pants will arm it and leave it in their pants. If you detonate while hidden and stay hidden, you will not be blamed for the crime.
