    From the main menu select "Multiplayer" then "Custom Games". Now select "Halo CE", and then select any map. While on the Game type tab, click in the right stick, select "Save As", and name the file ".fortune" and enter. When you do this, you will get an error message within Halo MCC, and the achievement will unlock.

    Here is an achievement guide with English commentary. Essentially, you have to set up a custom game and in the options tab rename the file to ".fortune"
