I was playing trials. One person in my fireteam gets kicked when the match starts. We barely push through and get to the 4 win to 4 wins with the other team being rude (tea bagging). My teammate instantly gets sniped and it is just me against their whole team. They rush and I pull out my trust thorn and what happens next could only happen once in a life time. I fire my thorn 5 times and knowing for certain I killed two of them, I prepare myself for 1v1, but then I notice something. It says I got a triple kill. I got a collateral kill with thorn and killed their entire team. Tl;dr I got a collateral with thorn and killed all three people by myself
