I have finally managed to beat the absurdly difficult
qwertyuiopasdfghjkl;'zxcvbnm,. large/highI started out by taking the green gem and flying the LS straight down through the emitter. I then dug out 4 cells from the right wall and flew down there, and into the cave at the bottom-right. I let the drones out pre-emptively from a path at the bottom, and once all the drones had started pathing to the LS I finished building a shield in front of the medium decayable terrain where the creeper hits it on 2 sides (this step is very important - I had to make sure the drones would get inside of that cave fast enough that I could build shields to block the creeper off after the drones follow the LS).
I start using LS drone evasion on the high health drones - but the small drones up top will take too long to reach the LS so I can't use it on them or the creeper will flood the chamber I'm in - so I built 3 reactors, and a bunch of shields to wall the creeper and drones, and start nullifying the gateway. Some of the drones crashed into the shields before the nullifier finished, and the gateway sent out 4 drones - one of these drones targetted my LS so I could just use drone evasion on that one, and I crashed the LS into the other 3 drones leaving my LS at 0.69 health to protect my other buildings (you can avoid this by building fewer reactors - but you will very desperately need the extra energy income for the next few minutes)
Originally I thought I would need to dig the LS down further, so I was placing reactors with that in mind - it turns out I never needed to dig the LS further down so there is some room for improvement in the way I played through this part - I pretty much waited as long as possible before building shields every time so I could build more reactors, and sometimes built shields in front of my other shields if the fields allow for it to make some more room - this only happens at the top, on the right the creeper is far too dense for the fields to push it back significantly (there are 3 emitters just to the right of you each at about 150M intensity if you hadn't noticed). I built a single phantom coil to stop the phantoms, and deactivated it just as the last phantom died - I did not have a single packet of energy extra sent to the phantom coil - I was saving as much as I possibly could for reactors. You have to spend almost all of your energy defending at this point, and it's important to get reactors running as fast as you can, because you'll eventually run out of space for shields.
From here I bjuild up and finally have enough energy production that I can consistently build more reactors while rebuilding shields - I finally built a dark beam and enough reactors to power it - I would like to point out that if I had to move the shields a single space further to the left, that I would no longer have enough space for the LS to evade the drones indefinitely.
With some carefully timed movements, I put all my mirrors in place to protect all my buildings and the decayable terrain on both sides of me, and finally killed off the drones and put the beam in position to kill any future drones. From here it's a simple experimental map to build up and kill off the emitters.
This is easily the most difficult map I've ever beaten - if anyone feels insane, then feel free to try this map (my 5 and a half minutes of game time took me several hours to get to work)
