'Tribulation Knights' is the first part of a Christian stealth-based third-person adventure series for the PC, by Atomic Design Laboratory.

A "Tribulation Knight" is an agent of a secret organization created by a now destroyed Christian church association. Their mission is to insure the freedom and safety of the new Christians existing during the time of Tribulation. This period after the rapture known as the Tribulation will be a time where new Christians worldwide will experience persecution for their faith.

The storyline is an interpretation of the Bible concerning the end days. A worldwide cult organization is gaining control of the planet and is planning to incarcerate Christians who do not join them. The Tribulation Knights aim is to prevent that. The missions range from gathering intelligence to releasing fellow operatives from interrogation cells, to saving groups of incarcerated citizens from the clutches of the powerful Enforcers.

The game features stealth as one of the most important and critical aspects of gameplay. Shooting and killing of game characters is absent.

The 'Tribulation Knights' website says: "The game also serves as a warning to those who are not yet saved, that life will be difficult after the rapture."

So it seems that, if you are not a fan of evangelists, this will not be the game for you.
