No date announced yet. Check out more in the Crunchyroll article as they are co-producing along with Aniplex. Series synopsis from AniList:
Back then, Dok-Ja had no idea. He had no idea his favorite web novel ‘Three Ways to Survive the Apocalypse’ was going to come to life, and that he would become the only person to know how the world was going to end. He also had no idea he would end up becoming the protagonist of this novel-turned-reality. Now, Dok-Ja will go on a journey to change the course of the story and save humankind once and for all.
Oh hell yeah. The web novel is fantastic, the manwha is a great adaptation, and if they provide this a bit of care it should be a great show.
That said, it takes a while to really get going. The physical manwha started coming out and the entire first two volumes are by and large just okay. Depending on the pacing of the first season it might not blow up the way it could or should simply because it won’t be very good yet.
