Titanfall

You need to win a single match on Haven, of any game type. Note that since you cannot pick your map except in Frontier Defense (which can be challenging to win without a good team) you will need for the map to show up in rotation. Playing a single game type without leaving the lobby will ensure that all maps show up in a random but repeating cycle. This may take 3-4 hours, but is the only way to guarantee that you will play on this map in the chosen game mode.
