Insidious alien forces conspiring to enslave humanity grow increasingly dangerous and defiant. Willing to do whatever it takes to defeat these ancient invaders, the Cerberus rebels carry on the fight for freedom.
The Cerberus fighters embark on an urgent quest to discover what happened to expeditions lost in Italy, on land that once belonged to the Etruscan empire. On site they encounter the monstrous Charun, armed with the hammer of the gods, and Vanth, the angelic winged huntress with a heart of evil. These alien gods are intent on opening a portal to bring their kind to earth, harnessing the power of victims' minds while using their bodies as shock troops. As the river Styx is poised to flow again, the Cerberus team must prevail or an invasion from a barbaric dimension will lay siege to Europe and beyond.
