The Mass Effect 3 Extended Cut DLC adds a fourth ending to the game.
Eurogamer's Tom Phillips, who happily had the day off to coincide with the new content, has reported in to provide us with the details.
THERE MAY BE SPOILERS AHEAD.
NO. THERE ARE SPOILERS AHEAD.
"When you have the three standard choices you can also turn around and look at the Star Child. I don't know if you still used to be able to wield a gun at that point, but I thought it'd be funny to take a pop at the brat. He gets angry.
"'So be it,' he says, basically meaning Shep has blown his chance, and the game ends with a recording of Liara passing down knowledge of the Crucible to future generations.
"The 'Winter Snow' epilogue (where the guy and kid discuss the 'legend' of Shepard on an alien planet covered in snow - you see it after the credits) now has a woman and child speaking, confirming that at some point the Reapers were then defeated with that technology."
The ending can also be triggered through new conversation options with the Catalyst. A video showcasing this "Refusal ending" is below.
Also worth noting is that BioWare has replaced the game's ending message with a new message, direct from the Mass Effect development team.
It is reproduced below, alongside an image.
"Congratulations on bringing an end to the Reaper threat. Commander Shepard has become a legend, and from here you can continue to build that legend.
"It has been a long journey - for Shepard and for the team here at BioWare - and like Shepard, we couldn't have done it alone. The Mass Effect trilogy began as the vision of a small team, but over the years it has grown. That growth has been fuelled and shaped by the feedback and support of our player community. Thank you for joining us on this journey, and we look forward to sharing further adventures with you in the Mass Effect universe."
