As the intensity of anticipation for the release of Kane's Wrath grows, more information has been released. We know enough about the game in order to compile a Unit Tech Tree of the units in Kane's Wrath.
Its based on what we have gathered from all sources we can find. So there may be a picture or two missing, but check out what each of the faction tech tiers looks like. Look to see a fully updated and comprehensive version to appear soon after the release of Kane's Wrath.
