Oh sorry, I misread! :/

In that case, maybe do another thirty years in the future, Metro 2066, which was roughly when Hunter said it would be habitable to live on the surface again - do the last of the Metro dwellers (worn down to a few thousand after all the wars and mutant attacks) leaving the Metro for good to begin rebuilding civillisation. You could also include the return of the Dark Ones (remember, the Baby Dark One said he'd return one day?) to help them rebuild.
