So, let's take a look at the local neighbourhood.
There's a Mk V grendade launcher fab right next door, so let's hack that while clearing out the guardposts. The response to that actually catches me off guard a little, for a first hack at 50AIP spawning the best part of 1,000 Mk IV ships seems somewhat excessive. Luckily my whipping boy with it's piles of areas mines can handle that reasonably well.
Other juicy goodies in the area. An advanced starship constructor that I may or may not hack in the future. A couple of fabs in the other arms, but nothing I can really justify going after. And, in the top left arm of this little cluster, a lovely little pair of planets. An ARS on Juub, and a hive golem on Nepiramond.
The hive golem for me is an instant winner. If the AI is going to start flinging waves of multiple thousands of ships around, the next best thing to a heaping pile of Martyrs is a regenerating 'kill everything on this planet' switch. Sadly I don't have time to retrieve it before the first CPA, but I do take Juub and gain myself some armor ships. Total AIP: 70.
Oh, and Juub also has a trio of Xampite asteroids. A little juggling of cloakers to get them back to my whipping boy, and when the 6,000 ship CPA shows up at around 2:20 it gets pretty well vaporised by a single Martyr and my fixed defences.
3 hours into the game, Nepiramond has been taken and the hive golem is under construction. Should hopefully be ready in time for the second CPA. Unfortunately I now have 90 AIP, and the AI sends its first 6.5k ship wave at me. 'Only' tachyon microfighters, but still let's try not to enrage the AI much beyond 100 AIP. A bit more scouting reveals a data centre on Vilmar which is quickly popped to take me back down to 80AIP. The rest of this hour is then spent pouring metal into the hive golem, using assault transports to take out the guardposts on Murdoch (which I'm going to use as my forward operating base), and building up a turret beachhead on the junction planet just outside my whipping boy to take out some of the special forces and eventually dissuade the AI from reinforcing that planet anymore. Oh, and also a quick 500 point knowledge hack, which gives me just enough research to unlock Mil III command stations.
4:15. Hive golem comes online, backed by a heaping load of matter converters as the zenith trader still hasn't deigned to wend its way down my arm of the cluster. 100 AIP. Second CPA hits, this time 13,000 ships. What happens when 10,000 threat meets a hive golem on a denuded DMZ planet next to my whipping boy?
Death. Death happens. About 6,000 ships die from that onslaught. The only real problem I have here that the AI has unlocked spire grav drains, which completely screw up the wasps attack. If they lock on to a ship halfway across the grav well and try to get into melee range at 44 speed while ignoring everything else around them they lose a vast amount of effectiveness. The only thing more annoying that that is the tachyon microfighters the special forces has, which have a nasty habit of roaming between planets using the exact same route my cloaked assault transports are trying to take. So many fighter + assault transport tachyon drilling fleets lost to those guys.
Anyway, the CPA is defeated without even needing to resort to Martyrs. My two outlying planets get wiped, but really that's expected at this point. As long as I can always fall back to my three main defence in depth worlds, everything else can be rebuilt.
In the next hour Murdoch is taken, a pair of fallen spire shard chases undertaken, and another data centre taken to the undertaker. 110 AIP at hour five, with the 3,000 knowledge from Murdoch spent on unlocking, possibly for the first time ever, the human modular fortress. Missiles and lasers and heavy beam cannons ahoy at only 100,000 energy. Oh, and the traders finally show up. Unfortunately they sniffily refuse to enter my actual homeworld, so I end up having to build the Zenith power generator on Ginwig, my middle defence in depth planet, instead.
Oh, and this guy randomly shows up on Murdoch. That would be an amazing stroke of luck if, uh, I was actually going to use the exile.
Anyway, additional scouting efforts have found another ARS, a pair of data centres, the AI superterminal and an interesting dyson sphere / advanced factory combo up in the top-most cluster. And now that Murdoch is mine, attacking those will no longer cause deepstrike...
