A month or so ago, I was playing through the scenarios, and though I forgot which one its called, its the one past the one called 'Siege'. It has most of the races on it versus Drengin + Yor versus the Dread Lords.
I'd been playing for awhile, and I'd finally built up some ships to the point where I was actually destroying some of the Dread Lords ships. And I'd noticed a pattern where the Dread Lords would send 2 ships against me, and one of them would be destroyed, but the other would be badly wounded with one 1-3 HP left. So on its way back to its own home base, it would go past one of my other planets, So I'd look at it, and see it only had 1-3 HP left, and think if I sent out another ship of mine, I could destroy it. So I'd do that, and send two ships against it, with something like 80+ attack power(Mass Drivers), and at the end of the battle, it was the dread lord's ship that wound up victorious. So, I'd try this again and again, and it wouldn't matter how many ships I sent against it, but one DL ship would be destroyed, but the other would survive with 1-3 HP.
EDIT: Nevermind. There's another topic on this. I'm talking about the Apocalypse scenario.
