Well, I WAS playing Yellow Comet Hard Campaign but I went and started a new hard campaign for extra points and accidently saved over it!

Now I am back on the last orange star mission, Liberation. Can any one help me please?

i remember that mission...i had trouble with it too, so i dont think i could help you very much.

All I can say is that you have to take control over the factory near the pipe seam. Build a bomber if you capture the airport and destroying the seam should be easy.(I really don't get why destroying 1 tiny pipe seam can be so stinkin' hard.)

Just get a bomber and bang. The pipe seam is even in range of the airport but if you want a higer score then use the bomber to kill a couple of units first to get your power score up a bit. Make sure you get Max though. He's the best with bombers (At the section you're at).
