    From the Main Menu, go down to Multiplayer, open "Social", from here, your best bet will be Quick Play, as this is always Slayer.

    Simply play through 5 games, and once you've completed your 5th game, the achievement will pop.

    *IMPORTANT*, you need to play Social or Ranked, as Custom Games will not count towards this as those are NOT "matchmade games".
