But the xbox 360 verison was not advertised with all the dlc content from mass effect 1 and 2, the only thing that was Included was the following Cerberus Network bonus content for Mass Effect 2, including Zaeed – The Price of Revenge, The Firewalker Pack,
Cerberus Assault Gear, Arc Projector heavy weapon, and Normandy Crash site mission, and the Online Pass For Mass Effect 3 granting players access to co-op multiplayer.

Maybe the makers of the game had something to do with the 360 not getting all the dlc content from mass 1 and 2, so it is no good blaming microsoft it is properly not their fault as they never advertised it with the content.

These Mass Effect 2 add-ons not available in Xbox Live service,

only available in Cerberus Network

(which can be found in Mass Effect 2 main menu / Extras submenu, and requires Mass Effect 2 activation code).

you need to redeem that code in game through the Cerberus Network

Hello Mojaal,

Thanks for coming to the forums. Unfortunately, you would need to reach out to the Publisher EA, as the DLC is accessed in game. It is possible that the DLC is region specific.

Hope this helps.
