Following the shutdown of Xbox 360 Halo online services on January 13, 2022, this achievement is no longer attainable.

Trivia
The achievement's name is a reference to the novel Moby-Dick. After stabbing his nemesis, the eponymous whale, with a harpoon, Captain Ahab yells, "...from hell's heart, I stab at thee!" He is then dragged underwater by the whale and drowns with it. The second part of the quote was referenced in the Halo 4 achievement I Thrust at Thee.
