Over on the Steam forum I posted an answer with a link to a file and in a short time it received a fair amount of downloads (which surprised me). So I thought I would post it here as well.
This wasn’t meant for anyone but me – so it is very rough to say the least. But maybe I will “pretty” it up and make a new version of it.
It’s all the items from the build menu in relationship to the Tech Tree and when you are able to use those items. Basically a bunch of screen prints of the build items and then if a Tech triggers any new items, then those items are shown. This way it is a bit easy to know what Techs will get you what items from the build menu.
Like I said, it wasn’t meant for anyone’s use but mine, but I posted it as an answer to a question and others seem to be downloading it. So it’s nothing fancy by any means.
Take it or leave it.
