Has anyone figured out how to get this achievement? How many times do you need to chat in each level? And in general, does it really work?

Такс, ну прошел я игру. Часть достижений закрыто. Когда я выбираю планету - там только сцены. Как получить пропущенное?

Or some equivalent very large alien monster?

Where do I find the save file so I can restart this game to claim missed achievements?

I got 4 achievements left to go and I was wondering how do you restart your game and play back from the beginning and I need to get those achievements done so if any tips please it would be nice?
