NFT technology seems decadent in general. There was the log about the difficulty of maintaining the equipment, which necessitated moving heavy stone panels in order to access the parts. Form over function.
In fact, NFT facilities kind of remind me of the Apple headquarters: the new Apple headquarters ("spaceship campus") had problems with door installation. Apple had mandated to contractors that the doors must have extremely tight tolerances. No reason. Just Apple wanting its building to conform to the design specifications of its smartphones.
It turned out that contractors were having major problems installing the doors, and they were becoming immobile or trapping people or not allowing air to circulate. So that's what happens when some uppity company decides to implement unreasonable aesthetic and design standards in what is supposed to be a functioning facility.
NFT must have been spending way more on construction and maintenance than Biocorp. As they say in war, "the side with the best uniforms - loses." Biocorp designs around standarized, modular parts, and easy maintenance. Sure, their technology is not always pretty. But it appears to have become the standard for all of South Underrail, which has a low budget. Biocorp was probably able to mobilize and field greater military forces than NFT, which was placed on the defensive (and lost).
I haven't played all the campaign yet, but Biocorp appears to have a more mass, quantitative approach, emphasizing affordability and ease of construction / use. Those factors often prove decisive in wartime.
Back to the issue, yeah, the Nagas are whack. And its melee attack is far more devastating. I think I saw it do well over 400 damage, while most of its ranged attacks were doing about 150. The poor performance of some of its defensive equipment would help explain their loss to Biocorp!
