mis3560: Ok, just bought the game and realize this may be a totally ridiculous question.
However, I can't use the starmap to travel to other systems. The only way I can travel is by choosing a job with Darius that requires travel.
When I go to the navigate tab, I can talk to Sumire but the starmap remains completely dark. I can't choose any other systems.
Game progression wise, I reached the Panzyr mission.
What am I missing? Do I need to keep playing before the map opens up?

mis3560: Thanks for answering. Thought I was doing something wrong or the game was bugged. I do have 1 more question.

If I'm stuck with the limited mission set until the main vsmpaign is over, there's no way to choose more difficult missions? The only ones available are 1/2 skull difficulty. Getting bored of fighting lights all the time and wanted some variety in the mechs I fight. Thanks again.
