Cabal

About
The Cabal are one of the many alien races that desperately wants to obliterate humanity. They are very large, possibly hominoid, creatures. Joe Staten described the Cabal as "rhinos carrying slug throwers and riding in big tanks."

The Cabal are located on Mars in a lost city from mankind's Golden Age.

Gameplay
The Cabal seem to employ, at least occasionally, shields as well as bladed firearms. The sharp edges on their shields might be used as powerful melee weapons similar to the w:c:Halo:Mgalekgolo Hunters in the Halo series.

Speculation

 * In some situations, Cabal may work with an enemy of unknown composition referred to as a Centurion.
 * It is likely that the Cabal are the species referred to by some media outlets as "War Rhinos."
