The Castithan Charge Pack includes access to a new playable race - the Castithans - alongside new missions, weapons and vehicles, including the game's first four-player vehicle, the Raptor Truck.

A price for the DLC has yet to be announced.

The Castithan Charge Pack is the first of five major DLC packs planned for Defiance, and is included as part of the game's Season Pass.
