This was a pure raider game. (Hence, the low-hanging reference)
10/10/10 Vicious Raider, 10 Marauder, 10 Human Resistance, 10 Dyson, 10 Trains, 5 (Hard) Golems. Bonus ship: Raiders. Ark: The shield one (Hegira?)
Immediately unlocked mark 3 raiders, nucleophilic turrets, and concussion turrets, and rest of science to unlock raid starships.
I do scouting raids for the first hour, keeping AIP very low and getting my scouts all over the map by sniping tachyon sentinels with raid starships. Find some good intel and take over my neighbors to start my expansion. Goal is to kill all data centers ASAP with raid starships so I can basically take some planets for free
Keep spending science to improve raid starships (***only get 1 extra for mark 3; bug). These ships are performing spectacularly at their function. TBH these are too good at killing fortresses (once you have Mark 4).
These units are amazing at hit and run. 1) Kill Tachyon and retreat. 2) Kill concussion guard posts (hard counters raid starships) and recloak by moving away from AI. 3) Super-Kite! (use speed to stay at max range and send damaged ones away to recloak and regen shields). 4) Once all major threats are gone (i.e. Eyes), send in fleet to clean up.
I found a way to exploit the Marauders that seems legitimate. I neuter worlds on the way to planets I want. I let the marauders take over and kill the command station. Now, I can get science on the planets!!! Just defend science station and clean up marauders and there you go. They can also make good buffers against the AI. (***Marauders at 10 were easily dealing with AI waves, which seems right at that setting)
Start hacking mercenaries and other good finds (***Shield Ark is amazing for hacking; just keep hacker in the bubble shield and you got it). I soon found template for vicious raid starships, so I also got these to mark 4 and holy cow do my combined raid starships kick ass! Even shield guard posts pop like a bubble. Raiders (fleetship and starship varieties) are pretty great at defense because you get them to the attacked planet super-fast.
My earlier intel revealed all the co-processors, so I got my raid starships in position to take these all out at once. (***I got WAY more reduction than 120 so that’s a bug—I debugged to get my AIP at the right level)
Hunters and Wardens felt pretty absent this game. I was able to cut off the Wardens in my intimal land grab and because I kept the AIP low (I think) the Hunters never had a fleet that could threaten me. It acted kind of dumb, trickling units through my wormhole instead of amassing the fleet together before.
With my low AIP (only 85) I felt justified in taking over a corner of the galaxy that had 3 golems. I neutered the planets with raids and then took out the three command centers simultaneously in order to quickly colonize them. Now with my golems, I felt powerful and started clearing out a path to the AI HW, colonizing the surrounding planets to get mark 7 raiders (these fleetships are pretty fun and powerful) and making sure the Overlord has no escape.
I bring everything with me because between the Dyson patrolling my base, the Human Resistance, low AIP, and my powerful turrets, I felt safe enough to bring all my mobile forces. Between my mark 7 raiders, my mark 4 vicious and normal raid starships, and unleashing ALL the mercenaries I found, killing the Overlord was easy.
Victory!
