Zombies are officially a Syfy mainstay. The network confirmed that Z Nation season 4 will happen in 2017.

Z Nation has been pulling out all the stops this season, switching gears from the levity that made this a standout show amongst the zombie genre to something a little more dramatic and gritty at times. That strategy hasn’t soured on fans nor Syfy as the network has picked up Z Nation season 4 for 2017.

The production from The Asylum will tally 43 episodes through the currently airing third season.
Z Nation Season 4 Release Date
A release date for Z Nation season 4 is TBA. Syfy noted that the season is expected to premiere in 2017, so September or October are both safe bets.
