Now James Dennesy is a member of MI86's undead zombie horde, although unlike the other reclaimed soldiers he has full capabilities and retained what he can of his humanity. With his team members Captain Rachael Erstweather and Royal Marine Lieutenant Lance Cogswell James Dennesy combats the Baron von Sterb and his witch Gretel who lead the Third Reich's Unglaublich Waffen Gruppe (Unbelievable Weapons Group).
