Metro: Last Light, Venice, there is a child who lost his teddy bear. I was able to find his bear and return it, but then ended up leaving the city before I could return to see if he and his mother finally moved out of the way of the door.
Metro: Last Light does not allow you to save games wherever you like, it would be difficult to get back to that moment in time in the game.
Does anyone know if that door may open? And if so, is there anything worthwhile behind it?
