Hey! I just finished Metro Last Light and got the bad ending, to get the good ending I have to start a new game or just repeat some leves to gain positive moral points?
You don't have to replay the entire game, but you might need to replay some levels through in a row as the progress is not kept track of separately. Unless you update the D6 chapter save it will have the old moral point count and finishing the game with it will yield the same result as before. For example: You can use the level select screen to go back to chapter 10, reach the finale from that point and get a different ending if you have found enough moral points along the way. Of course depending on how much you found to begin with, you might have to go further back.
