The Defiance TV show has now aired on the SyFy channel and I know not all of you will have been able to watch the show yesterday so the story may be a little confusing.
A couple of new trailers have been released this afternoon, one for the game, and one for the TV show, both of which provide background on the story.
When the game launched the Defiance lore background was not really explained very well in the game which made the game feel a little empty. Having watched the show before it aired it did clear up a few questions.
These two trailers are worth watching if you are going to try the game or even watch the show.
