Last week in Trials. Teammate pushes bridge to snipe. I go with him. I see an enemy on the other side. Knowing I'm out of sniper ammo, I duck behind cover. Teammate challenges. I throw a trip mine right as my Teammate catches a 1K Stare bullet to the face. Turns out this 1K stare had firefly. Explosion catches my trip mine in mid throw. Trip mine explodes not even a foot from my face. I just gave him the luckiest double kill of his life.
