Doctrine Z is a First Person Stealth Action Game.
Doctrine Z features Dreadnought Studio's assignment system, similar to quests in some games but different to many other first person shooters. Missions are not straight, linear levels, but feature varied gameplay with many options available to the player. The storyline is also heavily based off player choice, with the player's actions determining what happens in the story in a much more radical way than other games.

Assignments are grouped together into Cases, with cases ranging from several assignments to dozens of them.
