I screwed up.... I picked the option to kill off trevor, mostly b/c i wanted to see this ending, not realizing it would eliminate from the open world play. I don't have any save files, and i've replayed the big score, and that didn't help change the ending. Tried looking some things up online, but only things i've found were to replay the game, or to have someone send me a save file.
Is there still no options for this one? I wouldn't mind go back through, but i just don't have another 2-3 months to go back through the game.
