Tribulation Knights features stealth as one of the most important and critical aspects of gameplay. What truly sets Tribulation Knights apart from other games on the market are its game rules. Shooting and killing of game characters is absent from this game. A high tech slingshot is one of the primary tools available to a Knight and it is used to take out surveillance and alarm systems. An on-screen partner provides critical information in your time of need.
If the player is detected by any of the various types of surveillance, World Rule Enforcers, or by citizens loyal to the World Order, an alarm will sound attracting unwanted attention. If an alarm has been triggered then the mission might end prematurely, or the NPC enemies can become more aware when triggered. The enemy can capture the knight, which forces the player to replay the level or start again from a remote prison cell.
