Zupay: Sombras de la Independencia is a 2D Top-Down single-player game with Hack-n-Slash mechanics. You will take on the role of a gaucho whose soul was taken by the Zupay, a God of Death. During Argentina's War of Independence, your job is to try to stop the advance of the royalists from Upper Peru who want to seize your sovereignty while also trying to fight against your new host, the Zupay.

After the death of General Güemes, his renowned militia of gauchos, known as Los Infernales, was disbanded. Our protagonist, who had left the war behind to live a peaceful life, is once again forced to defend his homeland from the invaders. The royalists are hunting down the last of Los Infernales.

In the midst of an ambush on his village, our gaucho is taken by the Zupay, an Incan legend. The Zupay, a devil or demon, requires the fear of his enemies to be summoned. Betrayed and forgotten, the gaucho draws his faca to face his foes.

Together with his new host, he embarks on a journey to Upper Peru to put an end to the royalists once and for all.
