Actually this is all I was interested in, I don't even use my FSD boosters now all ships except two explorers are carrier based. Need to check the stats, was looking at some extra canyon runners.
I have a feeling all the new guardian/thargiod tech will be ground based, or we'll have to unlock a bunch of new stuff when Odyssey rolls out.
Most of these modules are side grades to engineering?
Guardian weapons are specific to Goid combat, and only some of those are really useful (but all are fun to use - my favourite is the Plasma Charger, visually really cool and enjoyable mechanic). I would unlock the Gauss first though as it yields the best results vs interceptors.
The HRPs I use on my Goid combat ships because a) I don't have to engineer them for hull (though they're not as good as a G5 regular HRP) and b) the corrosive resistance which stacks - meaning you don't have to worry about corrosive damage as it eats away at your hull at much reduced rates.
MRPs have better values compared to vanilla - but, like the HRPs, require power. So if you're struggling with power management these aren't as optimal.
Guardian Distro is great for getting an additional 4% power - but can't be engineered (like all other Guardian gear).
Guardian PP is good if you're too lazy to engineer it, I only use it if I want to cut corners re engineering.
Shield Reinforcements are good for shield tanks - I usually prefer hybrid builds though so use those slots for HRP/MRPs instead.
The fighters are fun and look and sound great, but are more fragile and I seem to remember at least 1-2 of the 3 can run out of ammo. Not 100% if this is a bug or not.
