Trinitrotoluene

Trinitrotoluene (TNT) is a yellow solid chemical compound, that is best known as an explosive material.

History
In Natla's Mines there are several TNT crates, which Lara Croft used to reach one of the higher ledges, and blow up a pathway to the entrance of the Great Pyramid of Atlantis.

TNT is used in Nevada Desert in a cave during excavation. Lara expedites the blast for her own gain.
