Unlockable: Prestige Mode

To unlock Prestige Mode, which is a multiplayer-only mode, you must reach experience level fifty-five. Instead of capping out at level fifty-five, which is the highest level, Prestige Mode allows you to start again from level one. This can be done a total of ten times, giving you ten different icons in in-game lobbies to show your extreme achievement.


Unlockable: Arcade Mode

To unlock Arcade Mode, beat the game once through on any difficulty level. Arcade Mode itself is split into two options - Full Challenge or Level Challenge - that add extra replayability to the game.


Unlockable: New Mission

To play an all-new mission, which is an extra mission after the main quest is completed, beat the game and view the ending credits thereafter. After theyve run their course
, you will then be given the opportunity to play one last single player mission before all is said and done.
