Bioware announced that the new, extended ending for Mass Effect 3 will be available to download this Tuesday, June 26.
This download will be available for all consoles and PC on the same date. And is also free, so don't worry!
BioWare said. "The Extended Cut is an expansion of the original endings to Mass Effect 3. It does not fundamentally change the endings, but rather it expands on the meaning of the original endings, and reveals greater detail on the impact of player decisions."
The extended ending adds additional scenes and epilogue sequences. "It provides more of the answers and closure that players have been asking for. It gives a sense of what the future holds as a result of the decisions made throughout the series. And it shows greater detail in the successes or failures based on how players achieved their endings."
So, for all those which completed the game and want to see more of the ending, or those who want to complete the game but haven't had time. I hope this will help you do that!
