I don't want to fail the mission but I doubt I'm strong enough for it yet. Everything in this area is beating the crap outta me (in my defence Im playing on Hard), I only wound up here after running away from some nasty people who wanted to steal my lunch money. I wanted to reload an earlier save but either my past few saves didn't work or the thumbnails for them are still for the previous saves that I've overwritten so I don't know which save is which.
So, if I leave the quest until I'm stronger, even though I've listened to the radio broadcast, will it fail? I assume if I go back to an earlier save and don't listen to the radio signal even if it appears THAT won't make the quest fail? Surely they can't be THAT crazy. Still, with some of the decisions they've made so far with this game I wouldn't be too surprised.
