How does that work? Simply register yourself at the official contest page and head into the game to earn the most ark salvage per hour during the contest period from 12:00 a.m. PDT April 30 to 11:59 p.m May 12 in the Most Wanted: Competitor and Most Wanted: Rogue's Gallery in-game pursuits. Of course, this is you, not your character's likeness, that we're talking about here, but it won't just be a simple screenshot pushed in the background. Artists from the series will render the winning player into an upcoming episode of the show.
[Update 4:15 p.m. EDT: The press release says that "the winner will have artists from the Defiance series render their character's likeness into a special place in an upcoming episode," but Trion's PR team has separately confirmed to Massively that it will in fact be you, not your character, whose likeness will be imported into the show.]
