Indigo Pearl, the gaming, technology and mobile entertainment specialist, will be working to raise awareness of Watchmen, Wanted: Weapons of Fate, and Terminator Salvation - The Videogame.
The agency will handle the lifestyle consumer PR while Warner Bros.'s in-house team will handle PR for the gaming press.
Indigo Pearl will initially be working on a six-month project. It will focus on online PR, including creating viral content and targeting blogs and game forums.
Caroline Miller, founder and director of Indigo Pearl, said that the agency would emphasise that though the games are part of a franchise they can be enjoyed independently of the films.
