Knight in White Assassination is an achievement in Halo 4[1] and Halo: The Master Chief Collection. It is obtained by assassinating a Knight in any Spartan Ops mission.

Tips Edit

  • Do this on a level that features only Prometheans so that there's room for trial and error.
  • Make sure to have Promethean Vision equipped so that you can see when a Knight turns its back without exposing yourself.


  • This achievement also rewards the player with the Knight Helmet Avatar Award when unlocked.
  • The title of the achievement could be a reference to the 1967 The Moody Blues song Nights in White Satin.
