The homeworld kill did not go as planned.
I moved 20 transports in to see what else I could drag loose and managed to snag the botnet golem and another 100 ships, they were gibbed on Nobbs. I then moved in my non-spire starships to start smashing the core guardposts. A mothership, 12 golems, and 45 hunter-killers spawned. My starships failed to escape the planet.
Nobbs held. - It turns out that spire ships have longer range and greater speed - and 120 Spire frigates will eventually kill a pack of hunterkillers. Almost everything else needs to be rebuilt. I move my dreadnaughts into the homeworld and smash almost everything before they too go down. Some recently produced bombers finish off the command station. - One down.
.. Then I notice the avenger has spawned. No worries, the defense on Nobbs can handle it. Sadly, as a result I rediscovered that Avengers Nuke the planet they die on.
I colonize the homeworld, move a number of forts and turrets there and hope for the best - turning attention to the other side of the map. - The next wave hits - and I realize I have a new whipping boy.
I finish taking out Throngus and Murdoch and discover that every 3-4 minutes there are carriers spawning from Leela, Worf and Zapp.
I move the fleet to the Venture company and try to build a wall. They smash my (built!) superfortress, and 2 MK 2 fortresses and power back in. I eventually head the spire fleet into those planets, clear out the barracks, and this enables me to have enough time to put up some defense. I take Leela, drop a warp jammer command station and build up defenses, as I take the planets in the backfield, snagging the 4 new fabricators, and the last ARS (Gravity Rippers), the next Exo-wave hits.
It cost me a Hive golem due to bad pathing and all four new fabricators.
38 Hours in:
Time to redouble my efforts, rebuild the walls, and dedicate the spire destroyers to spending time on Worf and Zapp.
