Asthenia is a dark fantasy adventure set in a decaying otherworld plagued by a mysterious corrupting disease. Players step into a bleak dimension ruled by ancient entities, shaped by loss, and slowly collapsing under the weight of an endless war.

You play as Adam, an ordinary man cast into this world alongside other humans. To survive, Adam must confront distorted foes, uncover tainted artifacts, and navigate hostile environments ranging from abandoned towns and industrial ruins to forgotten temples. Resources are scarce, danger is constant, and every decision carries weight as Adam searches for answers, and a way back to the one he loves.
