struggle for survival on the harsh and bleak surface with other survivors
or
live in a nice comfy large bunker with a few thousand people and all the mod cons except you can't go outside, or communicate with anyone outside?
See, I assumed everyone would choose the bunker but some friends said they'd rather chance death on the outside than live in a bunker, even if it was huge.
Polling wouldn't let me put only two options so you can also choose to die in the apocalypse and opt out of either scenario.
