Defeat the nameless man and end his suffering.
This achievement is story-related and not missable.
On the Antarctic Helipad when Claire and Steve try to walk down you will see Nosferatu is coming up the walkway. He takes about 4 sniper shots to the chest. Distance yourself away as he will throw poison which you will need a blue herb mixed to heal. If you get to far away you won't be able to see him even with the sniper scope He can knock you off the edge and cause instant death. If you become poisoned, a Blue Herb will not fix this thus adding an extra objective when you play as Chris.
