It's understandable if you've kind of forgotten about how Defiance is meant to be specifically tied to a show on the Syfy channel. Past reveals about the game have focused on gameplay, not actors and broadcast times. But if you're looking forward to immersing yourself in the full Defiance experience from the ground up, mark your calendar for April, as the first episode of the series is set to air then.
The series will premiere with a two-hour episode on April 15th at 9 p.m. EST. A Monday night slot isn't the most promising placement for a new show, but it might be a temporary placement until the show performs well. (Or poorly.) This also points to a launch for the game sometime in April, as the two are meant to exist side-by-side from the start. Keep an eye on the game's first beta test later this month to see what happens next.
[Update: Trion has clarified that in fact, Monday at 9 p.m. EST is considered Syfy's premier primetime placement and that the show will remain in that slot throughout the season.]
