How do you get the space epoch on empire earth?

To achieve the Space Epoch in Empire Earth, you need to advance through the game's epochs by gathering resources, building structures, and researching technologies. Progress through the earlier epochs—such as the Prehistoric, Ancient, and others—by developing your civilization and meeting the necessary requirements. Once you reach the Industrial Epoch, you can start focusing on advanced technologies that will eventually unlock the Space Epoch. Keep an eye on your resource management and military strength to ensure a smooth transition to this final epoch.
