Hi fellows, the game is still great. And because it's quite complex I sometimes can not remember how I solved certain quests the first time around. At the moment I can't remember how I did the quest for the alien on Mars. I've got the book of translation, but the other thing... big question mark. And I can't check it on another slot because when I have a look at the same quest it just says "completed" and the requirements are gone. Would you give me a hint, please?
