My husband and I are having a little trouble. We are both 58 and are not to good at these games, but love playing them. How do you get different characters while playing. For example, at the end of Level l in Raiders, you have to get Jocko and his wrench to fix the plane and fly away. How do you do this? We also needed to get Sabito, but had already chosen him. Any help would be greatly appreciated.

Thank You
