woohoo, I killed off the first homeworld literally seconds ago. It was easier than I thought and this was the toughest one. armored golem in, kill EMP guardian mk V, armored golem retreat. Mark 5 martyr to deal with most of the aggro ships. amored golem in, kill Core CPA guard post, armored golem retreat. Hive golem in, release wasps, hive golem out. wasps destroy all other core guard posts + remaining forces. artillery golem + 2 cursed golems in to take out forcefields protecting command station. using the 2 cursed to take out command station itself. Used my fleet to destroy any reinforces from the core world.
Got an incoming CPA of more than 2k ships, but I heavily fortified my homeworld... So I'm gonna use my forces to rush through to second homeworld.
current AIP is 784, but I should be able to make it. not many obstacles blocking my way.
EDIT: won the game, just barely. ended with 1134 AIP. If I would have taken my time destroying warp gates and killing waves and being careful not to put dangerous planets on alert, I would have easily made it... But I didn't want the game to last another 6 hours, so I rushed straight to the second homeworld and beat the game at about 14 and a half hours ingame. My homeworld would have lasted quite a while longer, but I let all my other planets die. putting core world on alert really makes for some unpleasant surprises lol. It's pretty much the Hive golem that saved my butt during all this... without it, my fleet would ahve bee wiped out at the second homeworld, which had less annoying guard posts than the first one, but 400 extra mark V ships on it.
Unfortunately I had accidentally overwritten my previous save, so I can't retry and take as few worlds as possible. I'll save that for my next game
