I got a Salvo from the Scions that appears after the safe room. I play as Lizzie so I don’t carry Salvo until the end (also no one does when playing for cards). I spent salvo ammo killing Rejects and Scions that appeared after the ammo room.
Demo thought that doing a SR was a good idea, so for the last wave of enemies Demo had Boomshot, Anchor had Boltok and I had only Snub.
While Demo killed most of the enemies with Boomshot, some Rejects were near the door. Anchor had his barrier and I started to melee them, and in-game kills feed showed my GT - bleeding icon - Reject. Funny thing is that I didn’t kill any Rejects when the kills feed appeared.
I know about some random bleeding with Mechanic’s ultimate, but this is new for me.
