Final Odyssey is a real-time strategy game taking place in 2038 AD. The world war that broke out destroys the global environment, depleting all of the natural resources and leading mankind to a state of near extinction. After the end of the war, humankind seeks a new place to replace the devastated Earth planning a "Final Odyssey Project". Humans send a cyborg called Amos to a TV 203 system which closely resembled the solar system. As the project reached its final stages, human beings descended to TV 203 system. But Amos underwent its own evolutionary process and was set on annihilating the human race remaining on Earth by producing clones with advanced weaponry. Human beings use the only cyborgs capable of destroying Amos called Targons to conquer the TV 203 system and destroy Amos.
Both the Targon and Amos tribes have 12 missions. There are 2 resources in the game: energy and minerals. To create new buildings, players must create robots which will transform into these buildings. The same robots can be used to gather resources. Once players have destroyed both the enemies on the map and the teleport buildings of the enemy, they can teleport to the next area and move back and forth between the areas.
