Avening Angel is a story-driven FPS se t in a Steampunk world. The entire story of Avenging Angel takes place in Thunderhead Point, an old Northern City States military facility, factory, and a research center know as "Facility XI", tucked away on a remote island in the Atlantic Ocean. The player character is an "Associate of the Inventor's Guild", a freelancer handyman, sent to the island on a routine maintenance mission.
As the story unfolds, it becomes clear that there is nothing remotely routine about this mission as the player is pulled into a web of international, as well as metaphysical, conflict.
