Assassin's Creed: Discover Your Legacy is a Facebook app that "analyzes a Facebook user's ancestry", tying the user to one of several possible ancestral roots and bloodlines. The app also includes some of the user's friends, tying them to the user's own bloodline and then dubbing them as either a trusted ally or a Templar.
The user can get a different ancestor every time he/she reloads the app.File:DyLSearchEngine.pngThe Search Engine seen in the movie.
Several modern day elements were implemented to the app's main content, such as an email from Alan Rikkin, detailing the user's ancestry, and also showing some links to websites that detail the user's early Assassin life, through the use of a search engine.
The search engine's appearance is very similar to Google
The app's official listed name is GS Discover Your Legacy. GS stands for Gamestop.
