Variety is reporting, and the network has confirmed, that Syfy series Defiance has been canceled after three seasons.

A hard sci-fi show about humans and alien races cohabitating on a terraformed Earth, Defiance was launched in 2013 as a transmedia experiment in which the plot would progress alongside separate characters in a videogame by Trion Worlds. Though led by Grant Bowler, the show was an ensemble series with main characters played by Julie Benz, Tony Curran, Stephanie Leonidas, Jaime Murray, Jesse Rath, Trenna Keating and Graham Greene.

According to Variety, the series delivered solid ratings in its initial Monday slot before it moved to Thursdays in its second season and experienced a sharp dropoff. Ratings declined further when it moved to Fridays this past summer. The Aug. 28 finale delivered 1.95 million overall viewers in the live plus-3 category, which includes streaming.

In a statement released by the network, executive producer Kevin Murphy said of the cancellation, "I got to collaborate with a group of stunning artists operating at the top of their game, and together we built a world. Because of that, there is no room for anything other than joy in my heart."

Syfy added: "Defiance was a truly groundbreaking series, delivering an immersive, cross-platform experience that transcended the television screen in a way that viewers had never seen before. We are incredibly proud of the work of the extraordinary cast, writers, artists and designers – and especially showrunner Kevin Murphy – who together brought the rich world of Defiance to life over its three season arc."

The cancellation follows Tuesday's announcement that Dominion -- the fantasy series spinoff from the film Legion -- would be axed after its recently completed sophomore season. Other shows wrapping up on the network include Haven and Continuum, with Lost Girl returning for a final season in 2016. Returning to Syfy for additional seasons are Face Off, 12 Monkeys, Dark Matter and Killjoys. Variety notes that in the works are shows such as the "Matt Damon-Ben Affleck produced pilot Incorporated, David Goyer’s Superman prequel Krypton and miniseries Brave New World from Steven Spielberg’s Amblin TV." The Ridley Scott-produced adaptation of the Arthur C. Clarke book 3001: The Final Odyssey is also on the way.
