I love heroic sacrifice as a  mechanic. It is better than "you lost and everything is over".

Hi Deleterious, I really like that you allow the characters a way of dying on their own terms :)

Well done

While I like this set up for the setting and mechanics, I don't like a character's life hanging on the balance of a much needed successful die roll. Here the risks are obvious and it fits. And it looks like you can keep playing, hopelessly, until someone calls an end to the scenario. It looks like you can restore someones Hope on a 5 or better, so that's nice.
