Edit: The video states that EA Montreal developed Mass Effect 3: Omega. This is incorrect. The DLC was developed by Bioware Montreal. Both developers worked under EA in Montreal, I just got mixed up!
Mass Effect 2 proved to be a bigger and better game than the original outing and all eyes were on the team at Bioware to see how they planned to close out the scifi trilogy. A short development led to a bigger launch than ever before, but controversy was just around the corner regarding the game's ending and EA's own anticonsumer business practices. This is the Story of Mass Effect 3.
