Global streaming service Netflix confirmed the return of its Korean zombie series “All of Us Are Dead” with a second season on Tuesday.

The zombie thriller, an adaptation of the legendary Korean webtoon of the same title by author Joo Dong-geun, revolves around Hyosan High School students fighting to survive in a zombie apocalypse.

As the drama series had introduced new zombie races -- those immune and immortal -- and had a different ending from the original webtoon, many fans have been expecting another season.

The four lead actors of the series -- Cho Yi-hyun, Lomon, Yoon Chan-young and Park Ji-hu -- appeared at Netflix’s Geeked Week event and announced the production of the second season to fans globally on Monday.

Director Lee Jae-kyoo had hinted in an online interview back in February that if the first season presented humanity’s survival, the second season would talk about zombies’ survival.

“All of Us Are Dead” became the fourth Korean-language series to top Netflix’s weekly chart in quick succession, following “Squid Game,” “Hellbound” and “The Silent Sea.” The zombie series also recorded 560.78 million hours viewed, making it the fourth most successful non-English TV series, coming behind “Squid Game,” “Money Heist Part 5” and “Money Heist Part 4.”

The 12-part series, which premiered on Jan. 28, remains available on Netflix.

The release date of season two has yet to be announced.
