My Shadowrunners have been going on a five (real-life) month streak of destruction and have gotten immensely powerful to the point where they are near gods, but also gotten incredibly shafted due to the fact that they've acted with pretty much no moral code of any form, so they're in a prison with no way out.
I've decided (and some of the players, when approached out of session, seem okay with my ideas) that the campaign will end after the players attempt to prison-break; whether with them all dying horribly (which I expect given that they tend to be not too focused on actually extracting and more focused on murdering hordes of enemies), or with them riding off into the sunset as mythical figures.
First, I'm ending the campaign, and while I've gotten approval from some players, I haven't asked for it from all of them, and some would never attempt anything if they thought it could get their near-epic character killed (even if the alternative is rotting in prison while being hired out as mercenaries and waiting for the final bullet that kills you). Otherwise things just get too ridiculous.
Second, we have a new guy in the party, who joined during just the past couple runs. This wouldn't be such a big deal but not only does he have a character, but even though he's not the most powerful of the group he's still way too powerful to transplant into a lower level campaign, especially since I was planning on shifting to a mostly non-combat campaign.
What do I do?
