Mass Effect DLC on 360

[quote user="NightHorror888"]But the more...controlling companies like the ones that make Borderlands and Mass Effect lock the DLCs to your account.[/quote]You seem misinformed.

The DLC for Borderlands 1 and 2 and that for all three Mass Effect games is available to all the accounts on my Xbox 360.

Over the whole of the Mass Effect series I have clocked in over 2000 hours, I nearly have all the figures they have released. However I only own 2 copies of ME1 (360 and PC), ME2 Only 360 I need to get a PC version and one copy of Mass Effect 3 Collectors
Edition (360 I need to get a PC version).

I felt Mass Effect 3 was 98% ok except from the ending, I felt that Mass Effect 2 was the best. Mainly because of LOTSB DLC, I loved Mass Effect 1.

Update regarding inclusion of DLC.

What DLC is included in the Mass Effect Trilogy?

• On PC, Mass Effect will include Bring Down the Sky and Pinnacle Station on disk. For Mass Effect 2, Cerberus Network will be included which features Zaeed – The Price of Revenge, The Firewalker Pack, Cerberus Assault Gear, Arc Projector heavy weapon, and
  Normandy Crash site mission. For Mass Effect 3, Online Pass will be included granting players access to co-op multiplayer
  
  

• On Xbox 360, Bring Down the Sky and Pinnacle Station are not included with Mass Effect, however they are available as stand-alone downloads through Xbox LIVE. For Mass Effect 2, Cerberus Network will be included and Online Pass will be included for Mass
  Effect 3.
  
  

• Information on PlayStation 3 DLC will be available soon.

Between the 360 and PC versions of Mass Effect 2 I've got all the DLC for the game, including the pre-order stuff.

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.
