What do I need to do to unlock the 5th planet? The only quests remaining are those unlocked from using passwords. At the research section, they require me to get 2 kinds of items 3pcs and 5pcs respectively. I can't remember how I did it before. I did the usual stuff like talking to everyone in the ship. I know this game is old but I need to practice before the sequel gets released. Thanks! EDIT: Problem solved!
