Canon Ending
While nothing is confirmed, signs point to the fact that the canon ending for Mass Effect 3 may be the Destroy choice.
The Destroy ending is the climax that saw the destruction of all synthetic life, from the Geth to the Reapers. In this, the Mass Relays are also broken beyond repair, just like we see in the teaser.
The destroyed Mass Relays would also explain the contact issues we hear in the audio throughout the beginning of the trailer, as many are stranded without the Mass Relays.
It’s also important to remember that dead Reapers are prevalent in the latest teaser. Of course, there were plenty of Reaper casualties before the ending of Mass Effect 3, thanks to Shepard and the united Milky Way Galaxy, but the Destroy ending kills all of them.
More than anything, Liara’s smile at finding the N7 armor is likely because she’s happy and hopeful that it belongs to Shepard. The Destroy ending is the only one that points to Shepard being alive, as their chest can be seen rising in N7 armor alongside a sharp breath being taken.
What do you think BioWare is hinting at in this teaser? Let us know in the comments below.
