So I know there's talk/plans for an arctic dlc, and speculation on whether there will be more. While contemplating dlc and time capsules I had this idea for a dlc and or new game :

After you've beat the game once, you can play through the brief life, after crash, of each other "survivor". Each segment would range from a few minutes to a few hours of play where you live through each aurora survivors experiences up until death. This means that anything you do will effect your next game. Manage to get a few titanium in the lifepod before those stalkers took you out? It will be there. Not only could you get to see the same crash and after events from a different characters eyes (briefly) but you would get to see those people's efforts reflected in your next play through. In most cases it wouldn't have a huge impact but I think it would be so cool.
