Avernus is a challenging action-adventure game where you take control of a reanimated guardian —empowered by the final spark of a dead god— who must brave the increasingly dangerous, labyrinthine halls of a hostile tomb. An ancient tomb of a long forgotten god is under attack. Its doors lie open, seals broken and no one is left to resist the invading legion. It is only a matter of time before they reach the inner core and fulfill their dire ambitions. As a final, desperate act, the buried god stirs one last time to give its remaining strength to a single warrior, who now must fight through the enveloping darkness and save his creator.
