Hi,
How do you manage to explore far, with tachyon detectors on every WH, I guess even Scout III can't pass (even teamed up?). I reckon I only unlocked Scout II but I don't see how much better Scout III would be, having say +15.000 health won't last long against high level defenses.
I also built the 5 Scouts starships, they are pretty weak for their cost I found...
