Dune Spice Wars: Research and development Dune Spice Wars guide, tips

On this page of the Dune Spice Wars guide you will learn a list of all available research / development in the game. You will find an explanation of how they work and the differences in research between the factions.

Last update: Thursday, May 26, 2022

This page contains information on Research / Development in Dune Spice Wars. You'll find the list of all research projects here, as well as the descriptions of the most unique ones.

Research is a key element of the game. You unlock it after conquering your first village. There are four tech trees available:

  1. Blue - dedicated to agents, espionage and infiltration.
  2. Green - dedicated to gathering and stocking up resources and materials.
  3. Red - dedicated to army issues and unit training.
  4. Orange - which focus on increasing the Solari's income.

Each faction has a few exclusive research projects which replace the default projects from the tree. We've placed them at the end of each list. Each subsequent research project needs more time to complete than the previous one. The higher-leveled the project, or the lower it is in the tree, the longer it takes.
