Spoilers of course.

So I killed the reactor. Then after I got teleported I ran into that little hallway in the corner with the exit and sniped the Queen from it, having to kill a few other devils that were in the way first. I got out, watched everything blow up, and watched the primitive Poser-graphics cutscene of my party getting knighted.

And back in New Sorpigal I noticed I have a Vile reputation for some reason.

I was Honorable when I went into the Hive.

Not exactly crucial now (there's no save transfer to MM7, right?). But...what did I do?

Hmm, I'm not sure.

I do believe that your reputation takes a hit when you free Archibald, and part of the ending sequence involves casting the spell that he gave you... I'm not sure.

And no, your party in MM6 does not transfer over to MM7.

Did you cast Armageddon or other Area effect spells which might have killed civilians ?

Do you still get the ending and the post-game mode, if you don't have the scroll that is supposed to contain the big boom?
