Here's a screenshot and a trailer which both show Sgt. Frank Delgado, one of the seven members of the U.S. Department of Occult Warfare's Jericho squad which can all be controlled in the game.

Delgado is the squad's heavy weapons expert and a skilled Pyromancer – one who speaks with fire. The source of his power is the entity of a living flame, a fire spirit, which lies encased within a protective shell on Delgado's right arm.

In combat, Delgado unleashes the spirit as a roaring flame. Responding to Delgado's commands, the fire spirit becomes a formidable weapon, razing the nightmarish enemies in its path. However, use of this fearsome living weapon comes at a cost: while the spirit is free, Delgado's arm burns with a searing pain, draining his energy. To be effective in combat, players must balance the use of the spirit against torturing Delgado to exhaustion.
