Major spoiler alert, not like it matters though. Ok so i made it to the space stage, got an uber ship and all that mess. Been to some of the grox colonies, and destroyed 4 or 5 of their colonies (grox are tough). Even with intersteller drive 5, i cant make it to the very center of the galaxy. I can outrun the grox, but eventually the jump-distance becomes so small i cant go further. So what am i missing? i got a few items in the list that are just Questionmarks. so i dont actually know what those do.. And destroying all the grox colonies isnt logical. Even waging wars with normal species is problematic when they make a new colony while you're in the middle of fighting a current colony. So whats next in unlocking those "secret" items?
