This trophy acts in a way that is similar to a platinum trophy, in that it unlocks automatically when all other trophies are unlocked.

Note: There have been some reports that this trophy does not autmatically unlock if you have not gotten all of the DLC trophies yet. No new patch has been launched since so it will most likely still be the case. Fortunately, the current DLC trophies are straight-forward and easy and will most likely already be unlocked before achieving all of the main game's trophies. If not, do not worry and go work on those and you will be rewarded with this trophy afterwards.
