Me and some friends were doing the KF raid and we were at the thrusty-wall jumping puzzle. My team is waiting for me at the door at the end as I had to make a phone call. I was sitting on the ledge opposite from where the entrance and exit were. As I was talking over the phone, with my mic in my lap, when I saw one of my friends accidentally fall off the exit platform, get smacked by a piston, and watched his corpse land next to my character. I could hear him shout over the mic while it was in my lap. I got off the phone just in time to use the slow clap emote and say "F-cking excellent."
