(It doesn't have to outright kill you, if you don't want it to. It was a relatively small detonation, it just took out a chunk of the town above a black site. The last thing you did was fall asleep, it could have woken you up and you might have been able to leg it in the opposite direction before you got too high a dose of rads. On the detonation post, this was said:
((We'll assume the others, if they return, were not caught in the blast, and escaped (hopefully) without harm.))
If you want to keep going and come up with a way to escape the town, you can do so. Don't forget that the timeskip is probably going to happen soon (I hope someone else remembers that).
Not to mention you keeling over from the detonation is a boring way to go considering I was hoping that after the timeskip Cyprus might learn that you're still alive and try to go for revenge because you blew that evac chopper up. Give it a little bit of tension, give us both a little thing to keep playing around with.
But hey, if you want to be dead then it's entirely your choice what you do.
Don't worry about making the mistake, you were left out of the loop. One of us should have updated you on what was happening, so sorry about that.)
"What's the ETA on return?" Cyprus asked the pilot through his radio, hoping for a positive response. He never liked these helicopter trips; it gave them a chance to brood in the wake of losses, and that was never good for morale.
