The Dawn of The Civilization -- rule

About The Dawn of the Civilization, from BoardGameGeek:

The Earth was recently attacked by aliens, and all defense systems seem ineffective against alien weaponry. As a result, governments worldwide have recruited explorers to venture into ancient ruins scattered across the globe in search of lost civilizations, hoping to uncover methods to resist the alien invasion. In this game, players take on the roles of these explorers, embarking on archaeological expeditions to various ruins. At the end of the game, the player with the highest score (representing the greatest archaeological achievements) emerges victorious.
