Hello, we have read the manual, and some things were still left unsaid for us..
1. Can an adult join to team as a payload specialist (the one that throws the moon rocks..)?
2. Is the an age limit (below or under a certain age)?
3. How can the payload specialist located in the outpost get new moon rocks after using all of the 20 balls he stated with? I mean, after the robots transfer the ball back to the fueling posts, how can he get the balls?
Thanks a lot,May Walter,Team 3038.
