So, minor status update:
I'm not sure steam announcements work any more or not. So, I didn't have to update my game for co-op play.
A nuke has been used to deal with 2000+ threat from a CPA I just didn't want to bother with, I was tired, and didn't notice an additional two thousand ships hit my worlds during the meantime. Due to inattention rather than difficulty, I rolled back.
My bombers (MkIV, supported by mk1-4 of fighter and missile) have been dying off horribly, I presume because the 400 AIP unlock was Zenith Reprocessors, and I'll need to adjust blob tactics to keep them alive a little longer, especially with all the maws. I might have to be smarter about my blob use....
I still don't have my advanced starship constructor, but I do have MKV leech starships if I bother to use them, MKV Vampire Claws, one ARS, and impending access to a system that was formerly covered by a superfortress but had MKV Raid Starships and MKV Snipers. Once I get Krypton (the planet with 620 hostile ships) cleared out, it should be a quick sweep to flip the southern systems. With everything to my rear secured, I'll be able to migrate my defenses forward - although I probably should have done that before...
Anything interesting learned? While reprocessors go down like anything else, they are a thing to be feared (by your polycrystal hulls). AI superforts are horrifying if your bombers have been eaten up entirely while you still have 300-400 fighters and frigates on the field, and hostile reinforcements are on their way towards your previously assumed safe rallying point. Now I need to decide between Decloakers and Scout Starships, but since I already have anti-sniper coverage from the Cloaker Starships...
Oh, and just because a former system of yours reports as clear, doesn't mean you should send in a rebuilder and try to put it back together. I might have rebuilt that command a half dozen times before I realized the... implications of lacking any scouting intel on a neutral planet. And went derp. Well, to be fair, it was shortly after I hit 401 AIP, and the AI'd just unlocked it's first stealth (non-camo bomber) ship.
What else? I'd cleared a few systems enroute to the advanced starship constructor before switching to my back systems. I'm not particularily looking forward to traveling through systems with 800+ ships, a good portion of which must be maws and reprocs. But then again, I've got warheads. I'll even try to be good and not nuke the next CPA, but... you never know.
Spider fleetship is very nice. They've been fantastic, and thanks to my minimal casulties and cloaking, a better choice than Forcefield Bearers. Now that reprocs have started wiping out an entire cap of mk1-4 bombers before I realize quite what is happening (AI giving me a taste of my own cloaking medicine), I'm starting to regret the choice. I do hope a decloaker unlock and some more careful positioning (fighters forward) should fix this problem. I kind of liked Operation: Troll the AI more than Operation: Reprocess the Human. In their defense, killing reproc engines has stopped those from running rampant quite a few times, and allowed me to defeat the AI force in detail quite a few times.
I'm deciding whether doubling down with high mark riots and spider turrets would just be sensless overkill or great fun.
