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


Also known as 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 should not be detonated until you have put a respectable distance between it and yourself.

Reverse pickpocketing plastic explosive will arm it. If you detonate it while hidden, and stay hidden, you will not be blamed for the crime. Even if the target is dead the C-4 will still be present on their corpse and can be detonated. In fact, reverse-pickpocketing isn't necessary; C-4 can also be easily planted nearby or on places where the intended victim frequently visits as part of their schedule, such as on beds or chairs. C-4 charges can be placed in plain view of anyone, as it is not a crime nor an aggressive action to deploy them. Therefore it is easy to set up ambushes with C-4, though its high cost is a deterrent. Non-player characters who see you placing it may make remarks such as "I can see what you're doing!" but they will take no other action. As long as you detonate it while hidden, you will not suffer any ill reputation effects. However, if the victim is hit when throwing down the charge or if the target wasn't successfully killed with the initial blast, they will become hostile to the player.

If multiple C-4 charges are dropped, they will all go off simultaneously when the detonator is activated.

It is possible to trigger a C-4 charge without a detonator by shooting it. As long as you remain hidden, non-player characters will not become hostile (a silenced weapon is useful in these cases).

As an improved holdout weapon, it can be brought into 'weapon free' areas such as casinos with a sneak skill of 50.

The small cave is south of the Hoover Dam. It is further south than the large cove just below the dam, round the next major bend in the river. One way to get there is to go north up the river from Cottonwood Cove. (It is also possible to travel Northeast of the Abandoned BoS Bunker, carefully climb down the cliff, and swim to the other side of the river. The lakelurks can attack from the bank while you're in the river so you may want to take care of them while on the cliff).

  • C-4 cannot be detonated remotely if you do not have a detonator. However, one can shoot or set off an explosion nearby it when it's placed on the ground to detonate it.
  • You can detonate from immense range. The max range is well over 200 meters or 14000 game units; however, actors won't render outside of 200m, making it pointless to detonate at this range. C4 should only be detonated when the target non-player character can be seen.
  • The game model used for C-4 is actually a re-textured bottlecap mine.
