To get the "Shadowmasters" topic you've to roll lucky and 'ask' ninja gals and drifters about those.
...I used the codex-ships for around 5 months before I was able to build my fortuna due to unlucky 'get free research topic'.
In 99I the codex ships are now locked behind Shadowmasters so youve got to have that prerequisite before you can even get the "whats up with X ship?" type purchase techs.
Which is kinda silly since I think it should be the other way around, with those ships
leading to the shadowmasters or cloaking device topic. And also silly because at this rate by the time I was able to actually receive a codex ship, I would actually be producing my Fortuna in the hangar since its like literally a straight shot 2 techs down from that. Which pretty much makes those ships irrelevant (unless for some reason I wanted more ships and would order them for my other bases).
I could get a Pachyderm right now if I wanted it, but I hate that thing and its expensive AF too (my deference to it has to do with on-map aesthetics, some specific ships such as the pachyderm should have a full job done on their map tilesets similar to the way the Triton or Hammerhead were put together in tftd with alot of specific, custom tiles to make it look like the ufopedia articles). I mean technically I can do without it right now, so thats what happens.
I believe it (will still?) go on underwater missions so it could be doing everything I want, though it also uses a Heavy weapon slot and everything regarding that is expensive and low accuracy early game.
There is also the fact that im only hovering at like 3-5 million cash and the only way im staying afloat is because of X-Grog between two bases. I need some other way to make money using materials (plastasteel? durathread?), I made an economy mistake for a couple months thinking I could make a profit, like it says in the bootypedia, on durathread by buying thread+plastasteel and making metal armor suits, but I was losing about 30% on it each time due to a miscalculation.
As for the zombies I did finish that mission somehow. The funky zombie growled and ran right up to my ship and got behind somebody but wasnt fast enough to attack. So he got blown away by a combat shotgun.
I managed to kill one of the strix with a K.Handcannon, took about 4-5 shells to do it though from the safe distance required. The other one got blown away with a blunderbuss that a gal in a grav harness was operating (through a window no less).
As for zombie encounters picture this... Excavator goes down, map rolls up as a standard civvie terror site neighborhood. Zombies in houses all over the dam place, and lots of them. Strix out in the street with plenty of space to reaction fire, and so is an armored zombie trooper. I got -nowhere- with that mission so ive learned to just engage those things when they land, if there's zombies I just leave, that way the ship doesnt stay docked for a long time doing its job.
(you only have an Aircar of 4 gals who are only wearing maybe metal/tac armor and a grav harness - and they dont really have the firepower with them to take out the trooper anyways)
Its worth pointing out that my hands who were wearing Tac Armor/Helm were able to shrug off and generally be unaffected by the spit attacks... but when the strix Explodes they definitely take damage from that even though they were unaffected by the spit
(the strix will also sometimes Explode Twice when killed, im thinking it has to do with killing it outright with alot of damage, and it is not a graphical glitch either because that damage is inflicted two separate times, it doesnt always do this though maybe 50% of the time)Regarding underwater missions:
Im well aware of the underwater situation and generally speaking there isnt much down there for the risk involved, plus all the expense of having a submarine. Ive heard of people fishing out interesting loot from it but at least half the time I get galleons with some treasure and thats it.
I think the lethal harpoons (combined with harpoon carbines) are probably effective against deep ones, but I tried stun bolts the first time and those had about 0 effect, and I didnt bother to bring melee because of underwater difficulties.
(I have Thief armor, just got it within the past month, so its technically doable but im not going to go for it because of the craft requirement. Unlikely to go on sea missions until near the end of 2602. I rushed Thief because I researched mansions and im expecting a mansion to pop up soon, it has been awhile though)
