77 rimworld, I am doing a playthrough where you don't start with food, there are no plants or trees and it is always a toxic fallout.
Now that everything started to look at least somewhat alright, a poison ship landed which I need to deal with. Some of the stuff that can spawn when you try to deal with it can one shot people. (Not even by making headshots). If it doesn't one shot someone, that person is now probably missing a lung or something else.
Another thing that can spawn takes ages to kill and has 1 of three weapons
1 massive spray damage
2 even more massive spray damage but a bit more controlled
3 firebombs
so..in short, I don't put the chance of survival for my people very high at this point
