If you have no equipment and down to your last HP and weren't able to get ahead of the hunters, then it's game over. Was this an oversight? No, the hunters can legitimately win that way. That said, the Gun's sniper shot ability originally had her roll two dice to attack rather than an automatic hit which didn't guarantee the hunters' win.
Thank you, I appreciate the clarification. I will point this out to my group and plan better next time ☺
