Trivia

 * The achievement is virtually the same as the Vidmaster Challenge: Annual achievement from the original Halo 3. It does however differ on three area's: 1) the name, since there aren't any Vidmaster Challenges anymore in the Master Chief Collection. 2) This achievement gives Gamerscore, unlike the Vidmaster Challenge that didn't give any. 3) The achievement tile has been changed.
