allright... I decided to be funny and try to capture every single planet on a 80 planet 'snake' map (only one entrance and exit on every planet) and now I'm stuck
I managed to get to the 41st planet and destroy the first AI homeplanet.... however, the AI progress has reached the 1200 and he just launched a cross attack. Now there are 3500 enemy ships waiting for me at the next planet (of which about 1500 mk V) and 2500 more in carriers... I gathered my entire fleet at zenith's decendants former homeplanet... which is about 2400 ships in total (mostly mk I, II and III) and 500 more in my hive golem (sadly my cursed golem got destroyed earlier in the game, he could deal some sick dmg). also set up a few hundred turrets, a few dozen minefields near the wormhole, 3 mk II fortresses and 1 mk III fortress and deployed several mk III FF around my command station.
I've scouted all other planets with my nearly invulnerable mk IV scout and enemy defenses on all other planets are pretty weak... if I would rush my fleet through the enemy planets I could destroy at least another 20 planets and in 14 hops from now there is an AI superterminal. it's just those 6000 ships waiting for me that's gonna be troublesome. when I nuke them I kill about 2000 but then the next planet is alerted and all the mk V ships, starships and carriers come in and kill me. I haven't build all my turrets to it's cap yet, but I doubt that's gonna make much difference at this point. I even went and build mercenary fighters to it's cap (resources are not a problem, but the other merc ships are just to expensive).
I also tried transporting my ships past the enemy.... but most of the transports get destroyed before they even make it to the next wormhole and then the enemy decides to just attack me anyways...
I don't expect I'm going to be able to win this campaign (I'm not that good in AI war yet in the first place), just trying to get as far as possible. any suggestions would be appreciated ^^
