You're assaulting a Phoenix Safehouse as a Halcyon Operative under Rose's command, and you decide to go loud. Rose calls from your radio; "Shredder unit is on site. Watch your back" You're in the basement/laboratory until you see a armored person, with a black Bullet-proof facemask, no helmet, and holding a Sawblade machine gun in the hallway where the stairs are. "HEY! ASSHOLE!"
