So, while my fleet is blobbed around a SuperTerminal, trying to reduce my AIP from the series of planets I had to take after placing my Spire City (did not know that taking every planet around it was a requirement - a hub planet with 11 wormholes was a bad choice of location!), an exo-wave hit that planet. Now, I didn't pay it any mind - it was the cornerstone of my defenses, complete with a SuperFortress, a Black Hole Machine, mini-fortresses, and several Mark 5 Turret planetary caps. It was also connected to my homeworlds (I had 2.)
Ten seconds later, You Have Lost flashes across my screen, while I was watching the SuperTerminal, deeming it more of a threat.
My last autosave was during the assault, and it revealed that the AI wave brought a single Raid Starship of a high mark with them, and it somehow nullified my Black Hole Machine and, while the rest of the assault force went for that world's command center, it slipped through the wormhole to my home command center and destroyed it in two shots, before that world's turrets could stop it.
I was... Impressed. I haven't been this utterly unprepared for my defeat since I encountered my first necromancer in Dwarf Fortress.
And that was how I lost my first completed game of AI War this morning.
