[Update: a rep for Trion Worlds has reached out to confirm that Defiance will be heading to the PC and Xbox 360 as well as the PS3.]
Trion Worlds' upcoming transmedia-y MMO gets a trailer and some plot details.
I'm vaguely suspicious that developer Trion Worlds (Rift) is trying to perfect Captain Power with their upcoming MMO-that-is-also-part-of-a-TV-show Defiance. The SyFy network series will influence the game which will in turn influence the show in some unspecified way. The trailer for the MMO shooter is for only the PS3, leaving the question of the PC and 360 versions of the game up in the air (or dashed altogether).
Here's the synopsis from the Defiance site:
Set in the near future, Defiance introduces players and viewers to a completely transformed planet Earth, inhabited by the disparate survivors of a universal war who endeavor to build a new society among the devastation. The game combines the intense action of a "AAA" console shooter, with the persistence, scale, and customization of an MMO, while its TV counterpart weaves the rich tapestry of the world into a series with the scope, characters, and drama of a classic sci-fi epic. Because they exist in a single universe, the show and the game will influence each other and evolve together over time, with actions in both mediums driving the overall story of Defiance.
