have u seen "Undead Park" by koogi? xd

It's technically not a manga, or manhwas, but "The Guy Upstairs" on webtoon is a must-read!! Though I warn you, season 1 ended on a cliffhanger and it's been on a hiatus for almost 2 years so far

for Apocalypse-focused though I'd recommend Surviving Romance (on webtoon)

Legroom!

and gachiakuta is probably the best apocalypse/action manga imo

Link Click STRONGLY RECOMMENDED DONGHUA (Also known as Shiguang Daili Ren) A Time-Travelling Thriller. OP & ED songs are LiT.
Now suggesting manhwa/hua :- (not sure u like BL, but some are really good nevertheless)

The 11th school trip
Dreadful Night (HEAVY VIOLENCE, But gives AMONGUS Vibes) {Thriller}
Global Examination (Apocalypse + Thriller, double Amnesia)
Dead man Switch (same as above genres, with time loop)
Follow the sheep into the Abyss (DEFINITELY RECOMMENDED NOVEL) Similar to Necromancer Survival, but with Apocalypse and Thriller. Prologue is available, but PLS give it a try, u won't regret it.
I'll see if I can recall other ones, but feel free to ignore this list if u aren't into BL. Have a good day.

maybe deadman’s switch
