(This is subject to some very big changes)

Start with the zombie character gaining a new talent point (he reached level 20) . 3 talent trees: necromancer, lich, ravager.

The zombie gains abilities to directly resurrect corpses, and control them (necromancy / lich powers) we see skeletons & zombies crawl out of graves.

The cult leader reveals himself & he kills him. He isn't able to leave before being captured. A spiritual cult ritual begins to try and resurrect the leader, using our character's blood or something. (They somehow know who he is & threaten his family?) Our character tries to escape, and gets close, manages to kill 1 or 2 cultists but gets killed himself. (or maybe instead of this he's actually sacrificed to try and resurrect the leader?)

Male character encounters humans which are more dangerous than the zombies. He's too trusting at first and gets punished for it. Ends with him needing to rest in a crashed car (rest for his mental state).

laser quest flashback, of both of them acting as a good team & shooting everyone and winning. Cuts back to him in present day disappointed the real life zombie apocalypse isnt as cool. It then cuts to the female character who is indeed living it like a cool action movie.

Female character: zombies are approaching her house from all directions, and she's trying to do too much. She has to trust her allies to hold certain positions if they're going to get through this.

(flashback) Some kind of resolution to her overcoming her trust issues. (ends with her being ok with him going out somewhere where there's women, even encouraging it to his shock, and she finally says she trusts him fully)

Issue ends with santa bursting through her door (boss fight)
