Game Completion

Is there some reward for completing the game 100%. 100% sync, collected all collectibles, and finished all quests?

Because I finished everything is there any story progression or any sort of reward. I'm hoping something happens in the game company. Please tell me if there is anything available, because although I really enjoyed collecting and completing everything It just seem lame if there isn't any "Hey congrats on 100%" reward.

well you get rewards for finishing stuff like Golden Flintlock Pistols for completing all naval missions and the best armor in the game for finishing the mayan statues. Other than that of course you get achivments/trophy's depending on what console you play on.

Not sure what you expected though...it wont give you extra missions for 100% the game.
