You drive to 7 different stations on a pretty small map. Each station gives you info about some moon base habitat/structure. Thats it. If u go to all 7, you unlock arcade mode, which is just as simple with the exact same objectives as the non-arcade mode. This app would b more fun if u could CONSTRUCT ur own moon base with the structures that NASA has developed IMHO. This is a very simple, mostly educational game that I tired of quickly. I think with some tweeks it could b a lot more fun.
