Home > Research
The Commander may research various technologies to make his team and their vehicles much more powerful. Following a traditional RTS-style tech tree, the progression through research is branched and varied. Two teams may take completely different paths for research depending on their play style.
The best place for information on each tech is the Empires Mod Research Tree Appendix.
Researching is handled by the Commander and requires the presence of a Radar facility. There is a Research button in the lower right corner of the commander interface, clicking this will bring up a dialogue showing current research progress and a link to the tech tree for further research. Clicking on the View Tree button shows something like this:
- A hex with a lock symbol in it means you need to research the top-level tree to get to the sub-items.
- Any hex with filled in blocks indicates a tree you have access to.
Research takes time, generally a minute or two for each topic, and costs a certain amount of resources. For this reason, it's very important to keep your Refineries operational.
Tech Tree Images
A number of graphical representations of the tech tree are floating around out there, some widely used, others not. Below you will find some of these. Only the first one is the actual official version.
