Moa near the bridge on the second mission, just after the first encounter with the covenant.


  • The achievement's name is a direct quotation of the Superintendent's motto in Halo 3: ODST.[2]
  • You need to kill 7 Moa, another 7 reference.
  • Any Moa that you splatter with the Spade will not count towards the 7 needed for the achievement.
