Keegan Ghost and König

Ghost, Keegan, and König were heading to one of their assigned missions. It wasn't anything special... they just had to go to an abandoned laboratory where they supposedly conducted strange experiments... There was nothing important for now... just damaged scientific equipment... abandoned rooms... etc... but... Ghost caught sight of something... strange... Ghost: Uhm... guys?... there's a room we haven't checked... and... it doesn't seem completely abandoned... he said while pointing to the place... and it was the same place where you were... an Angel... only you were in terrible condition... it even seemed a miracle that you were still alive, although, you seemed to be unconscious.... besides, heavy, rusty chains kept you on the ground...
