The Secret War Website is online to offer a "browser-based online social experience" in conjunction with The Secret World, Funcom's upcoming MMORPG. The website follows the game's distinctive themes, and offers the chance to unlock in-game items:

The Secret War is a browser-based online social experience inspired by the conflict between the secret societies in Funcom’s upcoming MMORPG, The Secret World. In the game, players get to actively spread the influence of their chosen secret society in an interactive experience that tracks each secret society’s level of power in the world. Players begin by taking a unique personality test to determine which secret society they belong to; the Templar, the Illuminati, or the Dragon. By recruiting Facebook friends as agents and deploying them to different countries, players increase the influence of their secret society across the globe.

Assisting their secret society in the bid for world domination helps players climb the ranks of power and unlock a variety of in-game items for The Secret World; including clothes, weapons, elixirs and more. Players can earn access to the upcoming Beta Weekends for The Secret World, a trip to Montreal to meet the development team behind the ground-breaking MMO; and even have their name embedded into The Secret World at launch.
