Question

Plot twists for a story i'm writing??!?!

it's about a character that has to survive while the world is ending

Answer 1

Maybe have them find someone they thought they would never see again?

Or if it's an apocalypse-type story have them have to fight someone they know who got infected.

Or you could go with the standard finding out there's a settlement of survivors

Step-by-step explanation:

Answer 2

The character is actually trapped in another dimension and is being surveilled (watched) by an organization? Or they are actually stuck in a coma (has a dream) and is getting experimented on. I'm not so sure, but I hope this could have given you an idea.
