Hey, progress has been good in my save. It seems the game has been updated, so I should say that my current save is from before the most recent update.
I'm at a wall with research in the March of 2000. There's nothing left to research, although I feel fairly certain I don't have it all done yet since I have many weapons I can't make yet- no laser weapons, no mass-drivers, no plasmas. So most of my soldiers are still using BlackOps stuff or Pulse weapons. My armor is capped to Cyber Armor.
I recognize that there's a tech tree, but it's not easily parsable for the information I want, which is essentially what should I be on the lookout for to meaningfully progress? I can upload my save if necessary, but short of that I can say that I've done an alien colony (and thus have the Tritanium Foundry up and running), I'm working on Psi-Amps now as the final research option available across my three labs, I've never gotten an underwater mission and I've done sparingly few ghost missions (enough to get some captives and their weapons, but never anything like the asylum ghosts).
I know for a fact I'm missing a couple MAGMA messages, too. I assume I need to do specific missions for those, one of which I assume is the wretched minitank factory, which if I can get away with it, I will avoid doing forever.
The current main enemies I seem to keep fighting are hybrids (so many hybrids, at least I can still research their workers) and the Syndicate. I've done the Cyberweb stuff to the point that they stopped showing up, although I never did a single thing with their portal network so I have no idea what that's about. It feels like UFOs have slowed down, as I've only seen Very Smalls of late.
