Nuclear Production Complex V6 Guardian

[Nerro]

I have successfully defended my base againts the Guardian here in V5 before by placing AA turrets randomly all over the map because its behavior is just flying everywhere shooting my buildings. But in V6 all it does is stay barely outside of the range of my battlements and snipe my defenses while moving bit by bit, only in range of very few of my AA towers while steamrolling the ones in its attack range.
How am I supposed to deal with that?

There is this one Reddit Thread that talks about this but I still have no idea at all on what I'm supposed to do.

if you have some megas you can simply outheal all damage the eclipse does (command them with G and than shoot at whatever the guardian is shooting at)

that way the guardian is actually never able to destroy anything because the enemy AI is really stupid (will pretty much stay on long distance chipping away at the same wall you are healing)

though taking the eclipse out will take a few minutes, since the only unlocked thing with enough range to hit it at that point are probably just parallax and tier 3 units like mega and zenith, which all do barely any damage

unless you have already unlocked end game tower like meltdown or foreshadow which make this guardian vastly easier

I helped someone do nuclear production yesterday, and we pretty much just chipped away at the guardians health with zenith and megas for several minutes (didnt loose a single structure tho since at the same time the megas can heal whatever the guardian attacks)
