Research in Goodgame Empire & Empire four Kingdoms
Once you have built the researchers' tower in Goodgame Empire or in Empire Four Kingdoms you can begin to carry out research. In order to start a research you either go to Economy in the Research menu or simply click on the researchers’ tower.
Research is divided into the two areas, Military and Economy, each of which contains two research trees. If you later upgrade the researchers’ tower to Level 2, additional researches are added.
Tip: Some researches are only unlocked when other development stages have been investigated. And of course, the research is more and more expensive the higher the level of research.
