How do I activate the Engineering Core? I think I have done everything else, but I just keep going in circles now.

Are you sure you mean engineering core.That's sort of a meeting place.I don't remember activating anything.What have you done so far?

I don't really know what I mean. I seem to be ready for the space walk, but whenever I do that, I come back in and I can't get to the bridge. I have no idea what I am missing or doing wrong. Is there a walk-through somewhere?

Did you try the Wiki.I have the guide and I still have to check the Wiki for things.Also check youtube.Sometimes you can find a video of everything you have to do.
