@Steve:"Are you sure? There's no other way? Can't I knock him out or put him in a sack or something and bring him to the Sword for interrogation? We might be able to interrogate him to confirm whether or not he's the last one, why they were sent here or if they managed to communicate what happened here to the UWM. You've got those... special two people on board. Can't they handle it?"
EDIT: How does he look like, anyway? I don't think we've ever gotten a description. Is he just a man dressed in that dull silver shade cloak and changeling mask?
If Steve confirms that there is no other way, say "I'm sorry. I really wish you had surrendered. But you left me no choice." while slicing his head off, looking him straight into the eyes as I do so. Or his braincase, if he turns out to be a robot.
Else, if Steve says there's even the slightest chance I could somehow bring him back to the Sword to be processed, do that instead. Knock him out, drug him, put him in a bag, cut his eyes out, shield him with my own body from my bloodthirsty teammates, whatever it takes.
((Can't believe I not only survived that fight with no missing limbs, but I also managed to win.))
(I don't think you were around for the serial killer mission but really, you should guess what happens when an amp user is near death and has no teammates around to injure. I hope you succeed on this dex roll, because you're the only one close enough.)
[Dex:1+1]
(NOPE)
The UE laughs bitterly for a moment before his head warps into horrifying shapes and detonates into pieces. Hovering there, where his head used to be, is his amp. It's glowing with an angry red light that is spreading outward at an increasingly fast rate. As the light touches the flesh of his neck and shoulders they mutate, twisting into horrible shapes, growing eyes and teeth and bursting veins and nerves like wet noodles that twitch and spasm.
So yeah, he just overloaded his Amp. I hope you guys like running.
[Flint dex:5+1
[Milno Dex:3+1
[Renen...doesn't really need a roll. Too fast]
[Bishop Dex:3+1
[jack:1]
"YOU SHOULD HAVE GONE FAAAAAAAAAAAAAAAAAAAST!" Renen says before vanishing down the hall as nothing but a metallic smear moving through the air.
Flint shoulder checks Jack into a wall and Runs off down the hall, screaming like a madman and sprinting like a track star. He manages to outrun the encroaching expansion of flesh murder for the time being. Bishop and Milno both manage to get away as well, though they start a little late and get...just a bit mutated. They manage to catch up with Flint though, their suit's pumping in all sorts of drugs as it tries to counter act the violent flesh rebellion.
And Jack...well jack isn't dead. But lets just say that he might be in a different shape when this amp overload finally loses power and the team can come back and get him. As for now, his consciousness is a bit too scrambled to be useful.
