Due to the series being labeled as "cast contingent", the series did not move forward until the roles of Cole and Goines were cast. In April 2014, Syfy green-lighted the first season, which consisted of 13 episodes, including the pilot filmed in 2013. The series premiered on January 16, 2015. On March 12, 2015, the series was renewed for a second season that began airing in April 2016. On June 29, 2016, the series was renewed for a 10-episode third season, set to premiere in 2017. In a surprising move, the entire third season aired over three consecutive nights. A fourth and final season was announced on March 16, 2017. The eleven-episode fourth season ran from June 15 to July 6, 2018 for four straight weeks.
