On any difficulty, beat the game. But on the last level, you must activate some sort of training event. You can stand over a weapon and press X repeatedly until it tells you to hold X to pick it up in a little tooltip, then do that. After that, finish the level. If this doesn't work, the other(much harder) technique is in about 500 places on the Forum.
