Pericles has been revealed to lead Greece in "Civilization 6," and players who pre-order the game get early access to the Aztec Civilization Pack.

A new playable character has been introduced and his name is Pericles, who was an influential Greek statesman. He also acted as the general of the Athens army during the Golden Age of Athens. His period of reign started after the battle against the Persian army in 479 BC. Greece was known to have strong economic and cultural growth under his leadership.

When playing Pericles, the unique districts will be known as Acropolis, which means "upper city" in Greek. It is named such because structures are built on hilltops that give an advantage to the defensive capacity of the civilization.

Greece's soldier units are called Hoplite and they wear bronze armors and carry long spears and short, round shields.

Meanwhile, players who pre-order the game prior to its Oct. 21 release will have access to the Aztec civilization led by Montezuma I, 90 days before it is unlocked to all players. Montezuma I is the fifth king of Tenochtitlan City, and the second emperor of the Aztecs.

He led Aztec for 29 years during which the Triple Alliance was formed. Aztec was succeeded by his 19-year-old son Axayacatl, who was then followed by his son Montezuma II.

Aztec's units were called Eagle Warrior, which comprised of young men of noble birth. In order to be called an Eagle Warrior, one must have gathered 20 prisoners to serve as human sacrifice. Aztec's warriors were sporty and their past time was often spent on the unique building called Tlachtli. One of the games they often played was similar to basketball without the use of hands.

"Civilization 6" will be officially released for PC consoles on Oct. 21. Meanwhile, those who wish to avail of the many perks may opt to pre-order.
