Unlike normal mines, this explosive was supposed to be used for construction, instead of combat. It was brought to the Sierra Madre in 2073, 4 years before the Great War, during the construction of the resort. It was used to aid in building the Villa because rocks and caves prevented building houses there. The charge helped construction workers build the Residential District and the corridors. After construction was completed the remaining demolition charges were deemed too dangerous and harmful to store in an explosives cache, and were slated for disposal.
The demolition charge looks similar to a normal frag mine but has a black striped yellow case and a bright yellow light, rather than a small red one.
In terms of damage, the demolition charge is almost identical to the standard frag mine, inflicting one additional point of damage. It also has no skill requirement, compared to the frag mine's minimum Explosives requirement of 25. However, these advantages are dramatically offset by the item's weight: each demolition charge weighs 1.5 pounds, compared to the half-pound weight of a frag mine. Nonetheless, demolition charges are one of the only two proximity-detonated explosives available in the Sierra Madre, and the one most damaging to the ghost people.
Alternatively, the vending machine code for the demolition charge can also be found in the southwest side of Puesta del Sol south, near a pool table on the third floor of a building with a wire ramp surrounding a courtyard of toxic cloud. It is on the same level as a sun bathing room, above the laser pistol.
