On Youtube there are video's where Shepard has to make a decision between what the ending will be, but instead in those video's he is shooting and ends up alive.
For some reason i missed that ending.
You need a certain amount of points to get that Destroy ending.
All endings are the same, with the exception of explosion colors. Apparantly people have forgotten how to end a series.
this is not the end off mass effect era this is the end of the shepherd era. knowing EA they will milk out shidloads of cash out of mass effect IP before retiring it.
