After having this modpack recommended to me and playing it for a bit, I decided to map out the tech tree in Cmaptools, it's complete enough that you should be able to get most of the research-able items in the pack, though I'm aware of some missing researches and mistakes.
If you find a mistake or item that isn't in this map, send me a PM detailing what the item was and what research gave you it.
[v2 - Added missing live engineer dependent techs, added dart clip dependencies]
