So the exclusive offers are not so exclusive after all. Both Game Stop and Best Buy were offering supposedly exclusive codes.
Game Stop's exclusive offer, a code to unlock the Comcast Optimized MLG map if you pre-order the game. You would think being exclusive there would be this one time longer then you want to enter code in the market place to unlock this map but the code is as simple as entering in "Comcast Faster" from the Main Menu from within the game. Not exclusive at all.
For the not so much Exclusive Code for the Best Buy offer for the Unlockable Assault Rifle is no more then a cheat code as follows: at the Main Menu (Hold RB) Down, Down, Up, Up, X, B, X, B, Y, Up, Up, Y
Another FREE map available from UBISOFT!
How to get it: From the games main menu….
