FWIW: I have asked a similar question in another post after searching the forum and other potential online sources, did not find anything, other than occasional mention of stuff in these forum discussions. Because I am new to games in general I think part of it is playing is figuring out how to play and what the 'rules' are, this in a sense a part of the game. I wondered for example what the bars were at the top of the screen (indicators / counter for events in mission like hangers destroyed). Found the partial explanation in a discussion.
I too would love to see some sort of simple guide as to the rules and 'stuff' on the screen - a lot of nuances here.
...I am addicted to this game and love it ...
Yeah, me too!
