It has been sixty years since King Gilgamesh defeated "the tower" single-handedly, and now the tower is reborn again. The "Summer of Anu" is a season that comes every few years during which the powers of the monsters within the Tower wane thanks to the grace of the great god Anu. Each Summer of Anu, the armies of the Uruk Kingdom secure their strongholds within the Tower, aiming to eventually conquer the upper floors. The story begins with the third Summer of Anu.
