So, I launch an attack to take an ARS on a particularly heavily fortified Mk4 planet. I succeed, mostly, and destroy a warp counterattack post in my latest multiplayer game with my friend. We have six champions.
So, of course, several thousand ships en-route to my homeworld.
Three minutes left on the timer, two waves are declared, each over a thousand ships. He sends his champions to deal with the wave, I rush to defend my territory.
Thirty seconds left on the counterattack timer, four enemy Nemesis units hit one of my outlying worlds.
Then the counterattack hits. Then the waves hit.
Then a CPA is declared.
Then, as I'm fighting off the AI, the Nemesis units take out enough of my planets to put me into a brownout.
I managed to save it, albeit at the cost of my home command station. They attacked from the ONE location not protected by all my defenses - right behind my home command.
I nuked them, to prevent them from rampaging around our territory and ending the game right then and there.
Ten minutes later, the CPA hit. We barely survived.
