Not sure if that's only an UI thing or not. It seems that having enough corpses should make an autopsy instant, but that doesn't seem to be the case.The Black Market seems to have only a random time component before it shows up (Between 25 and 35 days), but I think there is something else (some mission?) to make it appear on the map.

There is no Tier 3 Grenade Launcher - I guess Firaxis decided that Grenadiers were already really strong.If you do an Archon Autopsy, you get the Tier 3 Sword (Fusion Blade) even if you've never done the Stun Lancer autopsy for the Arc Blade (Tier 2 Sword) Technically, Tier 3 weapons don't require Tier 2 weapons.I don't think they actually matter, since you should have enough engineers/scientists by just playing the game. The Tree isn't listing all Minimum Science/Engineering Scores.Shen/Tygan count, so the base score is 5. The system seems to have been intended to be a lot more complex, but from all I can see, it's a flat +5 in effect. Some tech is locked behind a minimum score. Engineering and Science Score: It seems that each Scientist and Engineer adds +5 to some hidden score.Tomorrow or so I'll rush through the game again to verify and add anything that's missing, but if you have additions, let me know or send a pull request on GitHub (I'm using GraphViz to create the graph) Gameplay Notes I believe the tree to be correct but only mostly complete - especially the main quest (the Codex Brain stuff) isn't fully fleshed out, but then again, that part isn't why people want a Tech Tree :) It should contain all the items though, and all the buildings. The graph is laid out automatically and not neccessarily aestetically pleasing, right now I'm mostly focused on an info-dump (this is why there's info how many corpses for an instant autopsy, or the minimum required engineering level even though that number isn't displayed in the game). Orange is stuff related to the Main Quest.
