|Tiberium vein detonation|
Tiberium Vein Detonation in action during Operation Tacitus Interruptus
Yet another in a long line of Nod military applications of Tiberium, the Vein Detonation is an extremely lethal support power. After the capture of Alphonse Giraud by the Black Hand, the scientist was persuaded into developing weapons technology for the Brotherhood. He developed the principles behind the Vein Detonation in a short time, and when LEGION was sent to capture the Tacitus, the AI used it to destroy GDI refineries and equipment at three Tiberium patches in the area.
As Tiberium has spread throughout the Earth, underground veins of the mineral also are found worldwide. Using similar technology to the catalyst missile, the vein detonation causes the subterranean deposits under a given locale to explode. However, the vein explosion is significantly more widespread and violent than the catalyst missile, and it causes massive damage to any target above the vein. However, it can only be used on or near a Tiberium field; limiting its effectiveness to units marching on Tiberium or facilities very close to a patch. Despite its ineffectiveness it will severely damage even MARVs that tries to harvest the Tiberium.
In the first mission it was deployed in, the cost of the Tiberium vein detonation is only 2000, only half of its original cost.
