Demolition charge

The demolition charge is an explosive weapon in the Fallout: New Vegas add-on, Dead Money.

Background
Demolition charges are intended for use in construction rather than combat. These explosives were initially shipped to the Sierra Madre resort, where they were used to clear rock and other obstructions to allow construction of the Villa. Later, codes for the Sierra Madre vending machine were utilized to create demolition charges in addition to other tools.

Characteristics
The demolition charge is a placed explosive device, identical in function to a frag mine but with a black striped yellow casing and a bright yellow arming light. Though it was intended to be used in construction, the charge activates whenever a land-based target approaches within 4.6 feet and detonates in a 9-foot after a three second timer elapses. The target's explosive skill (or lack thereof) can determine how long the countdown actually lasts.

As a weapon, it does exactly one more point of damage than a frag mine, but only if you hit the opponent directly with the thrown mine. It weighs three times more, but requires no Explosives skill to use.

Like other proximity mines, it cannot be used in V.A.T.S.

Locations

 * Sierra Madre vending machines - Either in the Sierra Madre itself or in the Abandoned Brotherhood of Steel bunker in the Mojave.
 * Can be purchased once the appropriate holotape has been added to the player's inventory. The code can be found on a terminal in the Puesta del Sol service route.

Bugs

 * After the weapon is thrown, it is detected as a frag mine and will be put back in your inventory as such when you take it.
 * The Sierra Madre vending machines display the demo charge as weighing 2 lbs, not 1.5.
