Heroes of History

Description
Heroes of History is a free-to-play online game that combines a city-building experience with hero collection RPG elements, a PvE story campaign, and competitive PvP. It is considered an innovation of an earlier title Rise of Cultures by the same studio, but with a different focus as Heroes of History emphasizes heroes, battle and story.
Players are tasked with constructing a thriving historic city while collecting an array of both historic and mythological heroes. As their cities progress through the eras, their heroes grow stronger, which unlocks new potential in a variety of solo, collaborative, and competitive battle modes. In the game's solo PvE mode, Albert Einstein guides players through a time-travel campaign to save humanity from disaster.
