I also allowed the players a quick Rest to help rebuild the Frundsburg, if only barely, and for the Frundsburg player to regain consciousness with heavy burns as his burden.
I set the whole map up, placed several enemy mechs including a slightly repaired Sorvan on a single structure. I set up this while thing about them having remote charges they would try to use to collapse the admin building and thus kill the Captain and Ambassador in a last-ditch effort.
Then after ALL this, the same Frundsburg player procs a reserve he got during his downtime at Saber: a fucking Jump Pack.
The Jump Pack (SR specific) allowed him to choose a spawn anywhere, so he puts himself RIGHT ON TOP of Sorvan, procs everything else he has, and does over 30 dmg in a single attack...
This insta-kills Sorvan, so I rule it that he used the Frundsburg to just Highlander Burial Sorvan's mech beneath it via a jump-pack assisted stomp.
This, of course, set of Sorvan's self-erasure. An intenste blast utterly annihilates the Frundsburg and it's pilot, resulting in our first flash-clone and casualty of the campaign.
The players loved this, including the Frundsburg pilot, who saw it as a heroic way to go out and an interesting path for his character.
He was always focused on saving civilians, became a local hero, and now his flash-clone will have no memories of the heroic acts he made, or the impact he made on the people around him.
I ran one last segment on the ground where they got to speak with Captain Farris, who began by stating what they did was against Union's regulations, that there will be consequenced for both them and the rest of the crew... But admitted she would have done the same in their place.
Ambassador Bannerjee was a broken man when they spoke to him, spirit crushed by the horrific consequences of his actions.
