Genesis pit

Very little is known about the Genesis pit itself. About the only confirmed facts are: 1. That is was filled with Tiberium Creatures 2. That it featured a mixture of Tiberium, mutated Tiberium Fauna and Veins, and 3. That somehow Cabal discovered it and was able to use it to provide his armies with a supply of offensive Tiberium creatures through the use of drugged civilians.

With the destruction of Cabal, who probably knew the most about such matters, the information has probably been lost.
