At long last, the show that everyone secretly hopes will last forever, “Z Nation,” is about to debut its second season. With the outrageous Syfy zombie series leaving its first season on a major cliffhanger, fans have been eagerly awaiting the return of Citizen Z, Operation Bite Mark and good Old Murphy for quite some time.

Ever since the series wrapped up its first season in December of last year, viewers have been flooded by the Syfy network with countless teasers, promotional photos and interviews with the cast to whet fans appetites. To help ensure that no one is left behind when the show returns Friday, Sept. 11, below is a rundown of the top things to look forward to when Season 2 premieres:

1. Where’s Murphy?

“Find Murphy” seems to be the mission on everyone’s mind at the onset of Season 2. Without going into too much detail, Murphy (Keith Allan) is the last hope for humanity to find a cure for the zombie virus. Unfortunately, he’s a real jerk and couldn’t care less whether humanity lives or dies. To prove it, the final moments of Season 1 saw Murphy run away from the people trying to protect him and trigger a nuclear missile massacre in the process. Now, "according to a promo for the Season 2 premiere, Murphy is on the run, immune to zombies and loving being the only safe person in the world. Still, the team cannot allow him to simply escape when his blood contains their only hope at ending the apocalypse. So, let’s hope for their sake that finding him is easy.

2. Nukes and Zombies

As mentioned, Season 1 ended with a whole mess of the United States’ nuclear missile arsenal headed right for the team of survivors that make up Operation Bite Mark. It’s unclear how they’ll survive the initial blast, but there’s no avoiding the fact that “Z Nation” Season 2 will open with a second apocalypse coming. If you’re still skeptical, perhaps you’ll believe head writer Karl Schaefer, who told the crowd at the 2015 San Diego Comic-Con, “I would say a second apocalypse is coming.”

We’ve seen that our heroes can hold their own against a nation of zombies, but how will they fair against a nuclear holocaust?

3. New Players

Speaking of our heroes, obviously fans of Season 1 can expect to see the return of Warren (Kellita Smith), Mack (Michael Welch), Addy (Anastasia Baranova), Doc (Russell Hodgkinson), Cassandra (Pisay Pao), 10K (Nat Zang) and, their intrepid NSA eye in the sky, Citizen Z (DJ Qualls). However, with the team fragmented and, having lost a couple really great team members in Season 1, they’re overdue for some new additions.

Season 2 of “Z Nation” will feature some brand new characters that have already been teased on the site’s social media. Also speaking at the San Diego Comic Con, Smith revealed that her character, after losing two love interests in the past, will get herself a “boy toy” starting this year.

4. George R.R. Martin

After his brief cameo in Syfy’s “Sharknado 3,” author of “A Song of Ice and Fire” books, of which the popular HBO hit “Game of Thrones” are based on, George R.R. Martin is making a cameo appearance in “Z Nation.” According to Entertainment Weekly, the author will appear as a zombified version of himself at a book signing for “A Promise of Spring” the seventh, an presumably final, book in his series. As the outlet notes, that is not the official title of the book. Although “A Dream of Spring” is expected to be the book’s header, Martin has yet to confirm.

“I just want to prove to my fans that even in the Zombie Apocalypse, the Song of Ice and Fire books will still come out!” the author said in a statement, teasing himself for his own very slow writing pace as of late. The author is currently working on the sixth book in the series, “The Winds of Winter.” Book one came out in 1996.

5. 10K

Obviously one of the coolest parts of Season 1 was the mysterious 10K, named for how many zombies he plans on killing before he dies. Those that watch the show will know that he calls out the number of zombies he’s killed after he increases it – assuming he’s not avoiding getting his face bitten off at the time. According to his “Z Nation” Wiki bio, when last we left the sharp shooter, his count was at an impressive 3,003 (technically more, but he keeps a strict count). Odds are more than good that his number will increase dramatically throughout the course of Season 2. After all, he was only in the 1,000s when he was introduced at the beginning of last season.

6. Zombies, Zombies And More Zombies

This one probably goes without saying, but in a nation filled with Zs, the show is bound to feature a cavalcade of the undead. Whether they’re herding themselves into a clump the size of a state, bending to Murph’s apparently psychic will or receiving mercy, “Z Nation” promises to deliver hordes of the undead when it premieres at 10 p.m. EDT on Sept. 11.
